More Information
Summary:A front end module includes a first radio frequency (RF) terminal, a second RF terminal, a third RF terminal, a transmission path and a reception path. The transmission path is formed between the first RF terminal and the third RF terminal. The reception path is formed between the first RF terminal and the second RF terminal. The reception path includes a first set of switches, a second set of switches, a third set of switches and an amplifier. An amplifier is coupled to the second set of switches and the second RF terminal. The third set of switches is coupled to the first set of switches and the second RF terminal. When a transmission signal is transmitted to the first RF terminal via the transmission path, the first set of switches, the second set of switches and the third set of switches are turned off.
