For convenience of description, the above-mentioned devices are collectively referred to as a communication device.

Fig. 1 is a block diagram of a structure of a radio frequency system according to an embodiment, and referring to fig. 1, in this embodiment, the radio frequency system includes a first processing circuit 110 and a first switching circuit 120 (fig. 1 only shows a simple schematic diagram of the first switching circuit 120, which is only schematic and not limited).

In the present embodiment, the first processing circuit 110 is connected to the first antenna terminal, and the first processing circuit 110 is configured to support a transmission process of the first radio frequency signal; the antenna system comprises a first switching circuit 120, which is configured with a first common terminal, a first switching terminal and a second switching terminal, wherein the first common terminal is connected with a first antenna terminal, the first switching terminal is connected with the first antenna, the second switching terminal is connected with a second antenna ANT2, a selectable attenuation channel 121 is arranged on a path between the first common terminal and the first switching terminal, the attenuation channel 121 is configured to attenuate power of a first radio frequency signal, the first switching circuit 120 is configured to gate a path between the first antenna terminal and a target antenna, and the target antenna comprises one of the first antenna ANT1 and the second antenna ANT2.

Wherein the first antenna ANT1 and the second antenna ANT2 are configured to support transceiving processing of a first radio frequency signal; the first processing circuit 110 is configured to be switchably connected to the first antenna ANT1 and the second antenna ANT2 through the first switching circuit 120 to support a transmission process of a first radio frequency signal from the radio frequency transceiver 130. It is understood that the first processing circuit 110 may include a power amplifier, a filter, and the like to implement the transmission processing of the first radio frequency signal.

Wherein the first switching circuit 120 is configured to form a via connectable to the first antenna ANT1 between the first common terminal to the first switching terminal that is selectively accessible and a via connectable to the second antenna ANT2 between the first common terminal to the second switching terminal that is selectively accessible, and switchably connecting the first processing circuit 110 to a target antenna including one of the first antenna ANT1 and the second antenna ANT2 is achieved by gating the via connected to the first antenna ANT1 or gating the via connected to the second antenna ANT2. Through the switching of the antennas, the radio frequency system can adapt to more scenes when being applied to the communication equipment, for example, when the position of one of the first antenna ANT1 and the second antenna ANT2 is held or contacted to influence the signal transmission quality of the antenna, the other antenna can be switched to, so that the signal transmission quality is improved as a whole. Specifically, the first switching circuit 120 may gate a path between the first antenna terminal and the first antenna ANT1 by gating a path between the first common terminal and the first switching terminal; by gating the path between the first common terminal and the second switching terminal, the path between the first antenna terminal and the second antenna ANT2 may be gated.

A selectable attenuation channel 121 is arranged on a path between the first common terminal and the first switching terminal, and the attenuation channel 121 is configured to attenuate the power of the first radio frequency signal. Specifically, when the attenuation power of the attenuation path 121 is xdB, if the power of the radio frequency signal before passing through the attenuation path 121 is P, the power of the radio frequency signal after passing through the attenuation path 121 is (P-x) dB. When the target antenna is the first antenna ANT1, the first switching circuit 120 may gate the attenuation path 121 according to a requirement, so that a path connected to the first antenna ANT1 in the first switching circuit 120 may attenuate the power of the input first radio frequency signal. Optionally, the attenuation channel 121 may include an attenuation network, an attenuator, or the like, so as to implement a power attenuation function on the first radio frequency signal.

In this embodiment, when the attenuation path 121 is in the off state, a first path insertion loss value from the first antenna end to the first antenna ANT1 is smaller than a second path insertion loss value from the first antenna end to the second antenna ANT2; in the case where the target antenna is the first antenna ANT1 and the first antenna end is in a signal transmission state, the first switching circuit 120 is further configured to gate the attenuation path 121 so that the first antenna ANT1 and the second antenna ANT2 can each transmit the first radio frequency signal at a power within a preset power range.

When the attenuation channel 121 is in the off state, a first path insertion loss value from the first antenna end to the first antenna ANT1 is smaller than a second path insertion loss value from the first antenna end to the second antenna ANT2. In the related art, if insertion loss values of switching paths corresponding to the first antenna ANT1 and the second antenna ANT2 are different, when a first radio frequency signal with a certain power output at the first antenna end passes through a path from the first antenna end to the first antenna ANT1, an attenuated power value of the first radio frequency signal is different from that of the first radio frequency signal passing through a path from the first antenna end to the second antenna ANT2, so that the first antenna ANT1 and the second antenna ANT2 have a power imbalance problem when the first radio frequency signal is transmitted, and therefore, it is difficult to ensure performance of a radio frequency system in various scenes when the radio frequency system is applied to a communication device, and antenna switching performance is reduced. In this embodiment, in the case that the target antenna is the first antenna ANT1 and the first antenna end is in a signal transmission state, the first switching circuit 120 is configured to gate the attenuation path 121, so that the insertion loss value between the first antenna end and the first antenna ANT1 can be increased by the attenuation function of the attenuation path 121 to compensate for the difference between the first path insertion loss value and the second path insertion loss value, so that the first antenna ANT1 and the second antenna ANT2 can both transmit the first radio frequency signal at a power within a preset power range, and the problem of power imbalance when the first antenna ANT1 and the second antenna ANT2 are switched is solved.

When the preset power range approaches to the zero range, the first antenna ANT1 and the second antenna ANT2 may transmit the first radio frequency signal at relatively close power, so as to improve the problem of power imbalance when the first antenna ANT1 and the second antenna ANT2 are switched; when the preset power range is equal to a zero range, the first antenna ANT1 and the second antenna ANT2 both transmit the first radio frequency signal with the same power, so that the problem of power imbalance when the first antenna ANT1 and the second antenna ANT2 are switched is solved.

Alternatively, the insertion loss value of the attenuation channel 121 is equal to the difference between the second path insertion loss value and the first path insertion loss value, so that the difference between the first path insertion loss value and the second path insertion loss value can be made up by the attenuation function of the attenuation channel 121 so that the preset power range is a range equal to zero.

Optionally, the power of the radio frequency signal output by the first processing circuit 110 at the first antenna end is a sum of a target transmission power of the target antenna and a power compensation value, and the power compensation value is obtained by calculation according to the second path insertion loss value. The target transmission power is a power value required by the target antenna to transmit the radio frequency signal, and the target transmission power is a target value obtained by calculation according to related parameters of performance of the radio frequency system in various scenes.

In the related art, since the second path insertion loss value connected to the second antenna ANT2 is greater than the first path insertion loss value connected to the first antenna ANT1, the power of the first radio frequency signal when the first radio frequency signal reaches the second antenna ANT2 through the attenuation of the second path insertion loss and is transmitted may be low, so that when the radio frequency system is applied in some scenarios, the performance of the second antenna ANT2 may not be fully exerted, resulting in poor user experience. In this embodiment, the power of the rf signal output by the first processing circuit 110 at the first antenna end is the sum of the target transmission power of the target antenna and the power compensation value, and the power compensation value is obtained by calculation according to the second path insertion loss value, so that the power of the first processing circuit 110 at the first antenna end when outputting the first rf signal is increased, and the difference between the target transmission power and the power introduced by the second path insertion loss can be compensated, so that the transmission power of the second antenna ANT2 is still the target transmission power, and the problem that the transmission power of the second antenna ANT2 is low is avoided.

When the target antenna is the first antenna ANT1 and the first processing circuit 110 is in a signal transmission state, the first switching circuit 120 may perform power attenuation on the radio frequency signal after power compensation through the gate attenuation path 121, so as to solve the problem that the transmission power of the first antenna ANT1 exceeds the standard and cannot meet the regulatory requirement due to a small first path insertion loss value. Therefore, the radio frequency system can ensure that the performance of each antenna can be fully exerted on the basis of antenna power balance, and user experience is improved. It is understood that the radio frequency system of the present embodiment is limited to one first antenna ANT1 and one second antenna ANT2, and the same applies to multiple first antennas ANT1 and/or multiple second antennas ANT2. When the number of the antennas is multiple, the number of the ports corresponding to the radio frequency system and the number of the attenuation channels 121 are correspondingly increased.

The radio frequency system provided by this embodiment includes a first processing circuit 110 and a first switching circuit 120, where the first switching circuit 120 switchably connects the first processing circuit 110 to a first antenna ANT1 and a second antenna ANT2; a selectable attenuation channel 121 is disposed on a path between the first common terminal and the first switching terminal in the first switching circuit 120, and the attenuation channel 121 is configured to attenuate the power of the first radio frequency signal. When the attenuation channel 121 is in a closed state, a first path insertion loss value from the first antenna end to the first antenna ANT1 is smaller than a second path insertion loss value from the first antenna end to the second antenna ANT2; under the condition that the target antenna is the first antenna ANT1 and the first antenna end is in a signal transmission state, the first switching circuit 120 is further configured to gate the attenuation path 121, so that the first antenna ANT1 and the second antenna ANT2 can both transmit the first radio frequency signal at a power within a preset power range, thereby improving the problem of power imbalance when the first antenna ANT1 and the second antenna ANT2 are switched, and improving the communication performance of the radio frequency system.

Fig. 2 is a second block diagram of a structure of the radio frequency system of an embodiment, and referring to fig. 2 (fig. 2 only shows a simple schematic diagram of the first switching circuit 120, which is only schematic and not limiting), in this embodiment, the first processing circuit 110 is further configured to support a receiving process of the first radio frequency signal; a bypass channel 122 capable of being switched on is further formed between the first common terminal and the first switching terminal, and the bypass channel 122 is configured to transmit a first radio frequency signal; in the case where the target antenna is the first antenna ANT1 and the first antenna end is in the signal receiving state, the first switching circuit 120 is further configured to gate the bypass path 122, and transmit the first radio frequency signal from the first antenna ANT1 to the first processing circuit 110.

The first processing circuit 110 is further configured to support a receiving process of the first radio frequency signal, so that the first processing circuit 110 is switchably connected to the first antenna ANT1 and the second antenna ANT2 through the first switching circuit 120, and can support a transmitting process and a receiving process of the first radio frequency signal.

The bypass channel 122 and the attenuation channel 121 have opposite functions, the bypass channel 122 has no attenuation effect or attenuation approaches zero, and the power of the rf signal passing through the bypass channel 122 is not attenuated. When the target antenna is the first antenna ANT1 and the first antenna end is in a signal receiving state, the target antenna is only in receiving the radio frequency signal, and at this time, there is no problem of unbalanced transmission power during multi-antenna switching, and at this time, the first switching circuit 120 gates the bypass channel 122 without attenuation function, so that the first radio frequency signal from the first antenna ANT1 can be transmitted to the first processing circuit 110 with the lowest insertion loss, and the reception performance of the radio frequency system is not sacrificed.

Alternatively, when the first processing circuit 110 has a transceiving processing function, the first processing circuit 110 may include a power amplifier, a low noise amplifier, a radio frequency switch, and the like, and the signal transmitting function and the signal receiving function of the first processing circuit 110 are switched by controlling the radio frequency switch.

Optionally, the first switching circuit 120 may gate a path corresponding to the target antenna according to the first control signal received by the controlled terminal thereof. When the rf system is applied to a communication device, the first control signal may be generated according to current scene information of the communication device and a processing state of the first processing circuit 110. The scene information may be, for example, scene information that can be used to swipe short videos in a portrait screen, hold videos/play games in a landscape screen, listen to songs in a pocket/backpack, and the like. The first antenna ANT1 and the second antenna ANT2 may be disposed at different positions, so that a position of one target antenna among the first antenna ANT1 and the second antenna ANT2 is not held or touched, which may have a good signal transceiving performance, and the first processing circuit 110 is connected to the target antenna by controlling the first switching circuit 120, which may improve signal transmission quality. The processing state includes a signal transmitting state and a signal receiving state, wherein in the signal transmitting state, due to different path insertion loss values corresponding to the first antenna ANT1 and the second antenna ANT2, there is a problem of unbalanced antenna transmitting power, and insertion loss compensation needs to be performed through the attenuation channel 121 to improve the problem of unbalanced antenna.

The context information may be obtained by a control module 140, such as an application processor, in the communication device, and the processing status of the first processing circuit 110 may be obtained by the radio frequency transceiver 130 in the radio frequency system, so that the first control signal may be provided by both the application processor and the radio frequency transceiver 130; or the radio frequency transceiver 130 transmits the relevant processing state information to the application processor, and the application processor provides the first control signal after analysis processing; or the application processor may transmit the relevant scene information to the rf transceiver 130, and the rf transceiver 130 provides the first control signal after analyzing the scene information; and a central processing unit (cpu), a micro control unit (mcu), or the like, which can control the switching devices in the first switching circuit 120.

Specifically, in the case that the target antenna is the first antenna ANT1 and the first antenna end is in a signal transmission state, the first gating module 123 gates a path between the first end and the second end connected to the attenuation path 121, and the second gating module 124 gates a path between the third end and the fourth end connected to the attenuation path 121; when the target antenna is the first antenna ANT1 and the first antenna end is in a signal receiving state, the first gating module 123 gates a path between the first end and the second end connected to the bypass channel 122, and the second gating module 124 gates a path between the third end and the fourth end connected to the bypass channel 122; in the case where the target antenna is the second antenna ANT2, the first gating module 123 gates a path between the first terminal and the second terminal connected to the second antenna ANT2.
