In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth to provide a thorough understanding of the present application, and in the accompanying drawings, preferred embodiments of the present application are set forth. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. This application is capable of embodiments in many different forms than those described herein and those skilled in the art will be able to make similar modifications without departing from the spirit of the application and it is therefore not intended to be limited to the specific embodiments disclosed below.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise. In the description of the present application, "a number" means at least one, such as one, two, etc., unless specifically limited otherwise.

The radio frequency system according to the embodiment of the present application may be applied to a communication device having a wireless communication function, where the communication device may be a handheld device, a vehicle-mounted device, a wearable device, a computing device or other processing devices connected to a wireless modem, and various forms of User Equipment (UE) (e.g., a Mobile phone), a Mobile Station (MS), and the like. For convenience of description, the above-mentioned devices are collectively referred to as a communication device. The network devices may include base stations, access points, and the like.

At present, as shown in fig. 1A, a radio frequency system 1 commonly used for electronic devices such as mobile phones includes an MMPA module 40, a transmitting module 10 (the transmitting module is also called a TXM module), a radio frequency transceiver 30 and an antenna group 20, where the radio frequency transceiver 30 is connected to the MMPA module 40 and the transmitting module 10, and the MMPA module 40 and the transmitting module 10 are connected to the antenna group 20. The rf transceiver 30 is configured to send or receive rf signals through the signal paths of the MMPA module 40 and the antenna group 20, or send or receive rf signals through the transmitting module 10 and the antenna group 20, and in addition, the MMPA module 40 may also be connected to the transmitting module 10 to form a signal processing path to send or receive rf signals through a corresponding antenna.

Therefore, the existing transmitting module only supports the power amplification of the GSM signal, and because the low-frequency amplifying circuit, the high-frequency amplifying circuit and the 3G/4G/5G signal are all connected to the same selection switch, the existing transmitting module only supports the transmission of the single signal of the GSM signal or the single signal of the 3G/4G/5G signal, and the function is single. To implement the functions such as the endec, it is necessary to cooperate with a plurality of MMPA modules, which results in a high system cost.

In view of the above problems, the present application provides a transmitting module, a radio frequency system and a communication device, which are described in detail below.

As shown in fig. 2, an embodiment of the present application provides a transmitting module 10, including:

the medium-high frequency amplifying circuit 100 is configured to receive a GSM high frequency transmitting signal of the global system for mobile communications (GSM) of the radio frequency transceiver 30 through the first selection switch 310, amplify the GSM high frequency transmitting signal, and output the amplified GSM high frequency transmitting signal to the medium-high frequency antenna port 301 through the first filter 410, the noise reduction unit 500, the second selection switch 320 and the first coupler 610; or, the first selection switch 310 is configured to receive a target intermediate frequency transmission signal of the radio frequency transceiver 30, amplify the target intermediate frequency transmission signal, and output the target intermediate frequency transmission signal to the target intermediate frequency transmission port 302, where the target intermediate frequency transmission signal is a target intermediate frequency signal, and the target intermediate frequency signal includes an intermediate frequency signal of any one of a third generation 3G network, a fourth generation 4G network, and a fifth generation 5G network;

and the GSM low-frequency amplifying circuit 200 is configured to receive the GSM low-frequency transmission signal of the radio frequency transceiver 30, amplify the GSM low-frequency transmission signal, and output the amplified GSM low-frequency transmission signal to the low-frequency antenna port 303 through the second filter 420, the third selection switch 330, and the second coupler 620.

As shown in fig. 3, the first selection switch 310 is an SPDT switch, a P port of the SPDT switch is connected to the input end of the middle-high frequency amplification circuit 100, and two T ports are respectively connected to two ports for receiving the GSM high-frequency transmit signal and the target middle-frequency transmit signal; the second selection switch 320 is an SPXT switch, X is an integer greater than 1, a P port of the SPXT switch is connected to the first coupler 610, a first T port is connected to the noise reduction unit 500, and second to xth T ports are connected to the medium-high frequency transceiving ports 304 of the transmission module 10 in a one-to-one correspondence; the third selection switch 330 is a SPYT switch, Y is an integer greater than 1, a P port of the SPYT switch is connected to the second coupler 620, a first T port is connected to the second filter 420, and second to Y T ports are connected to the target low-frequency transceiving ports 305 of the transmitting module 10 in a one-to-one correspondence.

The P Port is called a Port (polarization) Port in the present application, the Port for connecting an antenna in a multiplexer switch in the present application is called a Port, the T Port is called a thru, a Throw in, and the Port for connecting a radio frequency module in a multiplexer switch in the present application is called a Port, such as a 4P4T switch.

It should be noted that fig. 3 only schematically shows 3T ports of the SPXT switch, 2 middle and high frequency transceiving ports 304, 3T ports of the SPYT switch, and 2 target low frequency transceiving ports 305, and in practical applications, the number of the SPXT switch T ports, the number of the middle and high frequency transceiving ports, the number of the SPYT switch T ports, and the number of the target low frequency transceiving ports may be more or less according to the difference between the actual values of X and Y, which is not specifically limited herein.

For example, the second selection switch 320 may be an SP8T switch, a P port of the SP8T switch is connected to the first coupler 610, a first T port is connected to the noise reduction unit 500, and second to eighth T ports are connected to eight medium-high frequency transceiving ports 304 of the transmission module 10 in a one-to-one correspondence;

the third selection switch 330 may be an SP7T switch, a P port of the SP7T switch is connected to the second coupler 620, a first T port is connected to the second filter 420, and second to seventh T ports are connected to the seven target low frequency transceiving ports 305 of the transmitting module 10 in a one-to-one correspondence.

Illustratively, the noise reduction unit 500 includes an ISM NOTCH for optimizing interference of a wireless high fidelity Wi-Fi signal with a GSM 1800/1900 signal, and the like.

For example, the GSM low frequency transmission signal includes GSM850, GSM900, etc. frequency band signals; the GSM high-frequency transmitting signal comprises frequency band signals of GSM1800, GSM1900 and the like.

In some embodiments, the medium-high frequency transceiving port 304 is configured to receive or transmit a target medium-high frequency signal, where the target medium-high frequency signal includes the target intermediate frequency signal or a target high frequency signal, where the target high frequency signal includes a high frequency signal of any one of the 3G network, the 4G network, and the 5G network, and the target low frequency transceiving port 305 is configured to receive or transmit a target low frequency signal, where the target low frequency signal includes a low frequency signal of any one of the 3G network, the 4G network, and the 5G network.

Specifically, the frequency band division of signals of the 2G network, the 3G network, the 4G network, and the 5G network is shown in table 1.

TABLE 1

As can be seen, in this example, since the target low-frequency transceiving port and the medium-high frequency transceiving port are connected to different selection switches, respectively, the transmitting module supports carrier aggregation of the target low-frequency signal and the target medium-high frequency signal. However, in the existing common transmitting module, the target low-frequency transceiving port and the medium-high frequency transceiving port share one selector switch, and the transmitting module cannot transmit the target low-frequency signal and the target medium-high frequency signal at the same time, i.e., the existing transmitting module does not support carrier aggregation of the target low-frequency signal and the target medium-high frequency signal.

In some embodiments, as shown in fig. 4, the middle-high frequency amplifying circuit 100 includes a first middle-high frequency power amplifier 110, a middle-high frequency matching circuit 120, a second middle-high frequency power amplifier 130, a fourth selection switch 140, and a third middle-high frequency power amplifier 150, wherein the fourth selection switch 140 is an SPZT switch, Z is an integer greater than 1, an input end of the first middle-high frequency power amplifier 110 is connected to a P port of the first selection switch 310, an output end of the first middle-high frequency power amplifier 110 is connected to an input end of the middle-high frequency matching circuit 120, an output end of the middle-high frequency matching circuit 120 is connected to an input end of the second middle-high frequency power amplifier 130, an output end of the second middle-high frequency power amplifier 130 is connected to a P port of the SPZT switch, a first T port of the SPZT switch is connected to an input end of the third middle-high frequency power amplifier 150, the second to the Z-th T ports are connected to the target intermediate frequency transmission port 302.

It should be noted that fig. 3 only schematically illustrates 3T ports and 2 target intermediate frequency transmission ports of the SPZT switch, and in practical application, the number of the T ports and the target intermediate frequency transmission ports of the SPZT switch may be more or less according to different specific values of Z, which is not specifically limited herein.

For example, the fourth selection switch 140 may be an SP3T switch, a P port of the SP3T switch is connected to the output end of the second middle and high frequency power amplifier 130, a first T port is connected to the input end of the third middle and high frequency power amplifier 150, and second to third T ports are connected to the two target intermediate frequency transmission ports 302 of the transmission module 10 in a one-to-one correspondence.

Therefore, in this example, the medium-high frequency amplification circuit supports both the amplification processing of the GSM high-frequency signal and the amplification processing of the target intermediate-frequency signal, which is beneficial to improving the device integration level and reducing the cost.

In some embodiments, as shown in fig. 5, the GSM low frequency amplifying circuit 200 includes a first GSM low frequency power amplifier 210, a first GSM low frequency matching circuit 220, a second GSM low frequency power amplifier 230, a second GSM low frequency matching circuit 240, and a third GSM low frequency power amplifier 250, an input terminal of the first GSM low frequency power amplifier 210 is connected to the GSM low frequency receiving port of the transmitting module, an output terminal of the first GSM low frequency power amplifier 210 is connected to an input terminal of the first GSM low frequency matching circuit 220, an output terminal of the first GSM low frequency matching circuit 220 is connected to an input terminal of the second GSM low frequency power amplifier 230, an output terminal of the second GSM low frequency power amplifier 230 is connected to an input terminal of the second GSM low frequency matching circuit 240, an output terminal of the second GSM low frequency matching circuit 240 is connected to an input terminal of the third GSM low frequency power amplifier 250, the output terminal of the GSM low frequency power amplifier 250 is connected to the first terminal of the second filter 420.

As can be seen, in this example, the GSM low-frequency amplification circuit includes a plurality of power amplifiers and matching circuits, and can implement power amplification processing on GSM low-frequency signals.

In some embodiments, as shown in fig. 6, the transmitting module 10 is further configured with a VCC power supply port 306; the VCC power supply port 306 is connected to a combining port 307, and the combining port 307 is an internal port of the medium-high frequency amplification circuit 100 after power supply ports of the first medium-high frequency power amplifier 110, the second medium-high frequency power amplifier 130, the third medium-high frequency power amplifier 150, the first GSM low-frequency power amplifier 210, the second GSM low-frequency power amplifier 230, and the second GSM low-frequency power amplifier 250 are combined.

For example, the input voltage of the VCC power port 306 can be the output voltage of the battery cell, typically between 3.6V and 4.2V.

Therefore, in this example, the plurality of power amplifiers share one VCC power supply port through the combiner port, which is beneficial to reducing the number of ports of the transmitting module and reducing the cost.

In some embodiments, as shown in fig. 7, the transmitting module 10 is further configured with an SDATA port 701, an SCLK port 702, a VIO port 703, a VBAT port 704, a Vramp port 705; the transmission module further comprises: the controller 700 is connected to the SDATA port 701, the SCLK port 702, the VIO port 703, the VBAT port 704, and the Vramp port 705, and configured to receive MIPI BUS control signals of the SDATA701 port and the SCLK port 702, receive MIPI power supply signals of the VIO port 703, receive bias voltage signals of the VBAT port 704, and receive Vramp signals of the Vramp port 705.

Therefore, in this example, the controller in the transmission module can receive and process various signals, which is beneficial to improving the device integration and reducing the cost.

As shown in fig. 8, the present embodiment provides another transmitting module 10, including:

the selective amplification sub-module 101 is configured to selectively receive a GSM high-frequency transmission signal from the radio frequency transceiver 30, amplify the GSM high-frequency transmission signal, and output the amplified GSM high-frequency transmission signal to the medium-high frequency antenna port 301; or, the target intermediate frequency transmitter is configured to selectively receive a target intermediate frequency transmission signal from the radio frequency transceiver 30, amplify the target intermediate frequency transmission signal, and output the target intermediate frequency transmission signal to the target intermediate frequency transmission port 302, where the target intermediate frequency transmission signal is a target intermediate frequency signal, and the target intermediate frequency signal includes an intermediate frequency signal of any one of a 3G network, a 4G network, and a 5G network;

the GSM low frequency amplification unit 201 is configured to receive a GSM low frequency transmission signal from the radio frequency transceiver 30, amplify the GSM low frequency transmission signal, and output the amplified GSM low frequency transmission signal to the low frequency antenna port 303.
