Abstract
A front-end module includes a duplexer, a band pass filter, and a terminating circuit element. A first signal path connects an output terminal of a power amplifier and a transmit node of the duplexer. The band pass filter is disposed on a second signal path between a branch point and a ground. The second signal path branches off from the first signal path at the branch point. The band pass filter has frequency characteristics in which, among frequency components of a transmit signal output from the power amplifier, frequency components that overlap at least part of the pass band of a receive filter of the duplexer are allowed to pass through the band pass filter. The terminating circuit element is disposed on the second signal path between the band pass filter and the ground. The terminating circuit element attenuates a transmit signal passing through the band pass filter.
