Document Type and Number:
WIPO Patent Application WO/2023/016209
Kind Code:
A1
Abstract:
Provided in the present application are a transmission module, a radio frequency system and a communication device. The transmission module is provided with a medium-high-frequency transceiving port, a target medium-frequency sending port, a medium-high-frequency antenna multiplexing port, a low-frequency antenna multiplexing port and a target low-frequency transceiving port, which cooperate with corresponding amplification circuits and selection switches to realize the transmission of various types of signals such as a GSM low-frequency signal, a GSM high-frequency signal, a target low-frequency signal, a target medium-frequency signal and a target medium-high-frequency signal. Moreover, first power information and second power information are respectively detected by means of a first coupler and a second coupler, and power information to be outputted is selected by a fifth selection switch and is outputted by means of a coupling single port. The aim of signal power detection is achieved, and functions of the transmission module are enriched.
