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

Fig. 1 is one of the block diagrams of an rf system according to an embodiment, referring to fig. 1, in this embodiment, the rf system includes a first processing circuit 110 and a first switching circuit 120 (fig. 1 only shows a simplified schematic diagram of the first switching circuit 120, which is only illustrative and not limiting).

In this embodiment, the first processing circuit 110 is connected to the first antenna end, and the first processing circuit 110 is configured to support transmission processing of the first radio frequency signal; the first switching circuit 120 is configured with a first common terminal, a first switching terminal and a second switching terminal, the first common terminal is connected with the first antenna, the first switching terminal is connected with the first antenna, the second switching terminal is connected with the 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 the first radio frequency signal, the first switching circuit 120 is configured to gate the path between the first antenna and the target antenna, and the target antenna comprises one of the first antenna ANT1 and the second antenna ANT 2.

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

Wherein the first switching circuit 120 is configured to form a path between the selectable first common terminal and the first switching terminal, which is connectable to the first antenna ANT1, and a path between the selectable first common terminal and the second switching terminal, which is connectable to the second antenna ANT2, the first processing circuit 110 is switchably connected to a target antenna including one of the first antenna ANT1 and the second antenna ANT2 by gating the path connected to the first antenna ANT1 or gating the path connected to the second antenna ANT 2. By switching the antennas, the radio frequency system can adapt to more scenes when being applied to communication equipment, for example, when one of the first antenna ANT1 and the second antenna ANT2 is held or contacted to influence the signal transmission quality of the antennas, the other antenna can be switched, and therefore the signal quality of transmission is improved as a whole. Specifically, the first switching circuit 120 may gate a path between the first antenna end 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 can be gated.

Wherein a selectable attenuation channel 121 is disposed on a path between the first common terminal and the first switching terminal, the attenuation channel 121 being configured to attenuate power of the first radio frequency signal. Specifically, when the attenuation channel 121 has an attenuation power of xdB, if the power of the rf signal before passing through the attenuation channel 121 is P, the power of the rf signal after passing through the attenuation channel 121 is (P-x) dB. When the target antenna is the first antenna ANT1, the first switching circuit 120 may gate the attenuation channel 121 according to the requirement, so that the 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, and so on, so as to implement a power attenuation function for the first radio frequency signal.

In the present embodiment, when the attenuation channel 121 is in the off state, the first path insertion loss value from the first antenna end to the first antenna ANT1 is smaller than the second path insertion loss value from the first antenna end to the second antenna ANT 2; in the case where the target antenna is the first antenna ANT1 and the first antenna is in the signal transmitting state, the first switching circuit 120 is further configured to gate the attenuation channel 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.

Wherein, when the attenuation channel 121 is in the off state, the first path insertion loss value from the first antenna end to the first antenna ANT1 is smaller than the second path insertion loss value from the first antenna end to the second antenna ANT 2. In the related art, if the insertion loss values of the switching paths corresponding to the first antenna ANT1 and the second antenna ANT2 are different, the power value attenuated when the first radio frequency signal having a certain power outputted at the first antenna passes through the path from the first antenna to the first antenna ANT1 and the power value attenuated when passing through the path from the first antenna to the second antenna ANT2 will be different, thereby causing a problem of power imbalance between the first antenna ANT1 and the second antenna ANT2 when transmitting the first radio frequency signal, whereby it is difficult to secure performance of the radio frequency system in various scenes when applied to a communication device, and antenna switching performance is lowered. In the present embodiment, in the case where the target antenna is the first antenna ANT1 and the first antenna is in the signal transmitting state, the first switching circuit 120 is configured to gate the attenuation channel 121, so that the insertion loss value between the first antenna and the first antenna ANT1 can be increased by the attenuation function of the attenuation channel 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 each transmit the first radio frequency signal with the power within the preset power range, and the problem of power imbalance when the first antenna ANT1 and the second antenna ANT2 are switched is improved.

The preset power range may be a range approaching zero or equal to zero, and when the preset power range approaches zero, the first antenna ANT1 and the second antenna ANT2 may transmit the first radio frequency signal with 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 the zero range, the first antenna ANT1 and the second antenna ANT2 both transmit the first radio frequency signal with the same power, thereby solving the problem of unbalanced power when the first antenna ANT1 and the second antenna ANT2 are switched.

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 complemented 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 is the sum of the target transmission power of the target antenna and a power compensation value, where the power compensation value is obtained by calculating according to the second path insertion loss value. The target transmitting power refers to a power value required by the target antenna to transmit the radio frequency signal, and the target transmitting power is usually a target value obtained by calculating according to related parameters of performance of the radio frequency system in various scenes, so that when the target antenna can transmit the radio frequency signal with the target transmitting power, the performance of the target antenna can be fully exerted.

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 reaching the second antenna ANT2 through the attenuation of the second path insertion loss is transmitted may be low, so that the performance of the second antenna ANT2 may not be fully exerted when the radio frequency system is applied in some scenarios, resulting in poor user experience. In this embodiment, the power of the radio frequency signal output by the first processing circuit 110 at the first antenna end is the sum of the target transmitting power and the power compensation value of the target antenna, and the power compensation value is obtained by calculating according to the second path insertion loss value, so that the power of the first processing circuit 110 when the first radio frequency signal is output by the first antenna end is increased, the difference between the second path insertion loss and the target transmitting power can be supplemented, so that the transmitting power of the second antenna ANT2 is still the target transmitting power, and the problem that the transmitting power of the second antenna ANT2 is lower is avoided.

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

The radio frequency system provided in this embodiment includes a first processing circuit 110 and a first switching circuit 120, where the first switching circuit 120 makes the first processing circuit 110 switchably connected to a first antenna ANT1 and a second antenna ANT2; a selectable attenuation channel 121 is disposed in the first switching circuit 120 in a path between the first common terminal and the first switching terminal, the attenuation channel 121 being configured to attenuate the power of the first radio frequency signal. When the attenuation channel 121 is in the off state, the first path insertion loss value from the first antenna to the first antenna ANT1 is smaller than the second path insertion loss value from the first antenna to the second antenna ANT2; in the case that the target antenna is the first antenna ANT1 and the first antenna is in the signal transmitting state, the first switching circuit 120 is further configured to gate the attenuation channel 121, so that the first antenna ANT1 and the second antenna ANT2 can each transmit the first radio frequency signal with 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 an rf system according to an embodiment, referring to fig. 2 (fig. 2 shows only a simplified schematic diagram of the first switching circuit 120, which is merely illustrative and not limiting), in this embodiment, the first processing circuit 110 is further configured to support a receiving process of the first rf signal; a selectable bypass channel 122 is also 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 case the target antenna is the first antenna ANT1 and the first antenna end is in a signal receiving state, the first switching circuit 120 is further configured to gate the bypass channel 122, transmitting 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.

Wherein the bypass channel 122 has the function opposite to that of the attenuation channel 121, the bypass channel 122 has no attenuation effect or the attenuation approaches zero, and the power of the radio frequency signal passing through the bypass channel 122 has no attenuation. When the target antenna is the first antenna ANT1 and the first antenna is in the signal receiving state, the target antenna is only in the receiving radio frequency signal, and the problem of unbalanced transmitting power during multi-antenna switching is not existed at this time, the bypass channel 122 without attenuation function is selected by the first switching circuit 120, so that the first radio frequency signal from the first antenna ANT1 can be transmitted to the first processing circuit 110 under the condition of minimum insertion loss, and the receiving performance of the radio frequency system is prevented from being sacrificed.

Alternatively, when the first processing circuit 110 has a transceiver 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 switching of the signal transmitting function and the signal receiving function of the first processing circuit 110 is implemented by controlling the radio frequency switch.

Alternatively, the first switching circuit 120 may gate the path corresponding to the target antenna according to the first control signal received by the controlled terminal thereof. When the radio frequency system is applied to the communication device, the first control signal may be generated according to the current scene information of the communication device and the processing state of the first processing circuit 110. The scene information can be, for example, a scene information can be a vertical screen for short video brushing, a horizontal screen for watching video/playing games, a pocket/backpack for listening to songs, 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 in the first antenna ANT1 and the second antenna ANT2 is not held or touched, good signal transceiving performance can be achieved, and the first processing circuit 110 is connected with the target antenna by controlling the first switching circuit 120, so that signal transmission quality can be improved. The processing states include a signal transmitting state and a signal receiving state, wherein in the signal transmitting state, since the insertion loss values of the paths corresponding to the first antenna ANT1 and the second antenna ANT2 are different, there is a problem that the transmitting power of the antennas is unbalanced, and the insertion loss compensation is required to be performed through the attenuation channel 121 so as to improve the problem of the antenna imbalance.

The context information may be obtained by a control module 140 in the communication device, such as an application processor, and the processing state 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 the application processor together with the radio frequency transceiver 130; the radio frequency transceiver 130 may also transmit relevant processing status information to the application processor, and the application processor may provide the first control signal after performing analysis processing; the application processor may also transmit relevant scene information to the rf transceiver 130, and the rf transceiver 130 may analyze the scene information to provide a first control signal; a central processing unit, a micro control unit (a single chip microcomputer), or the like may be used as a processor capable of controlling the switching devices inside the first switching circuit 120.
