and a third receiving module 93, connected to the second T port of the fourth rf switch, for receiving the ultra-high frequency signal received by the fourth antenna.

For example, the first receiving Module, the second receiving Module, and the third receiving Module may be a Low Noise Amplifier front end Module (LFEM), a Diversity receiving Module with an Antenna Switch Module and a filter (DFEM), a Multi-band Low Noise Amplifier (MLNA), or the like.

Illustratively, the first receiving module, the second receiving module, and the third receiving module are connected to 3 uhf signal receiving ports of the rf transceiver in a one-to-one correspondence manner, and are configured to output respective received uhf receiving signals to the rf transceiver to implement reception of multiple channels of uhf signals.

Therefore, in this example, by controlling the four ultrahigh frequency signal receiving channels to receive the ultrahigh frequency signals at the same time, the 4 × 4MIMO function of the ultrahigh frequency signals can be realized, and the receiving and transmitting performance of the radio frequency system on the 5G ultrahigh frequency signals can be improved.

As shown in fig. 16, an embodiment of the present application provides a communication apparatus a, including:

a radio frequency system 1 as described in any of the embodiments herein.

It can be seen that, in the embodiment of the present application, the communication device a separates power supplies of the processing circuits for the low-frequency signal and the other signals, and can transmit two paths of signals at the same time, so that the MMPA module can output two paths of signals at the same time, thereby supporting amplification of the 4G LTE signal and the 5G NR signal, and implementing EN-DC of the 4G LTE signal and the 5G NR signal. In addition, the MMPA module supports receiving and processing of one path of ultrahigh frequency signals, simplifies a radio frequency front end framework, and can reduce circuit insertion loss compared with an externally-arranged switch circuit de-combining path.

As shown in fig. 17, further taking the communication device as a mobile phone 1700 as an example for illustration, specifically, as shown in fig. 17, the mobile phone 1700 includes a processor 1710, a memory 1720, a communication interface 1730, a radio frequency system 1740, and one or more programs 1721, where the one or more programs 1721 are stored in the memory 1720 and configured to be executed by the processor 1710, and the one or more programs 1721 include instructions for executing any one of the steps in the following method embodiments.

Communication interface 1730 includes an internal interface including a radio frequency interface, a camera interface, a display screen interface, a microphone interface, and the like, and an external interface which may include a CAN interface, an RS232 interface, an RS485 interface, an I2C interface, and the like. The processor 1710 is connected with the radio frequency system 1740 through the internal interface, and the mobile phone is used for communicating with other electronic equipment through the external interface.

The Processor 1710 may be an Application Processor or a controller, such as a Central Processing Unit (CPU), a general purpose Processor, a Digital Signal Processor (DSP), an Application-Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, a transistor logic device, a hardware component, or any combination thereof. Which may implement or perform the various illustrative logical blocks, units, and circuits described in connection with the disclosure. The processor 1710 may also be a combination of computing functions, e.g., comprising one or more microprocessors, a combination of a DSP and a microprocessor, or the like.

Memory 1720 is used to store program codes and data for the handset. The memory 1720 may be either volatile memory or nonvolatile memory, or may include both volatile and nonvolatile memory. The non-volatile memory may be a read-only memory (ROM), a Programmable ROM (PROM), an Erasable PROM (EPROM), an electrically Erasable EPROM (EEPROM), or a flash memory. Volatile memory can be Random Access Memory (RAM), which acts as external cache memory. By way of example, but not limitation, many forms of Random Access Memory (RAM) are available, such as Static RAM (SRAM), Dynamic RAM (DRAM), Synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), Enhanced SDRAM (ESDRAM), synchlink DRAM (SLDRAM), and direct bus RAM (DR RAM).

The rf system 1740 may be the rf system in any of the embodiments, wherein the rf system 1740 is further configured to process a plurality of rf signals in different frequency bands. Such as satellite positioning radio frequency circuitry for receiving satellite positioning signals at 1575MHz, WiFi and bluetooth transceiver radio frequency circuitry for handling the 2.4GHz and 5GHz bands of IEEE802.11 communications, cellular telephone transceiver radio frequency circuitry for handling wireless communications in cellular telephone bands such as 850MHz, 900MHz, 1800MHz, 1900MHz, 2100MHz bands, and Sub-6G bands. The Sub-6G frequency band may specifically include a 2.496GHz-6GHz frequency band and a 3.3GHz-6GHz frequency band.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
