Abstract
A radio frequency (RF) multiplexer circuit is provided. The multiplexer includes a first circuit coupled between a first input terminal and a first output terminal. The first circuit is configured and arranged to transfer a first RF signal coupled at the first input terminal to the first output terminal as a first output signal when a first control signal is at a first logic value. The multiplexer includes a second circuit coupled between a second input terminal and the first output terminal. The second circuit is configured and arranged to transfer a second RF signal coupled at the second input terminal to the first output terminal as a second output signal having a gain higher than the gain of the second RF signal when the first control signal is at a second logic value.
