Title:
TRANSMISSION MODULE, RADIO FREQUENCY SYSTEM AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/016185
Kind Code:
A1
Abstract:
Provided in the present application are a transmission module, a radio frequency system and a communication device. The transmission module supports the transmission of a target medium-frequency signal in addition to supporting a GSM low-frequency signal and a GSM high-frequency signal, thereby expanding the transmission capability of the transmission module; and the transmission module cooperates with an MMPA module which supports a target low-frequency signal/target medium-frequency signal/target high-frequency signal/target ultra-high-frequency signal, such that dual-connectivity ENDC of a 4G network and a 5G network can be realized, thereby facilitating the reduction of system costs. In addition, the transmission module supports the simultaneous sending of two signals, for example, the simultaneous sending of a GSM low-frequency signal and a GSM high-frequency signal/target medium-frequency signal, the simultaneous sending of a target low-frequency signal and a target medium-high-frequency signal, the simultaneous sending of a GSM low-frequency signal and a target medium-high-frequency signal, or the simultaneous sending of a target low-frequency signal and a GSM high-frequency signal/target medium-frequency signal.
