1. A front end module comprising:
a plurality of duplexers, each duplexer configured to receive radio frequency signals within a specific frequency band of a plurality of frequency bands; and
a single impedance matching inductor configured to provide impedance matching for a plurality of receive signal paths between receive nodes of the plurality of duplexers and at least one low noise amplifier;
an antenna switching module in communication with at least one antenna and having a plurality of first switch positions, the antenna switching module configured to provide communication, responsive to a first control signal, between the at least one antenna and a selected duplexer of the plurality of duplexers; and
a single tuning inductor configured to provide tuning for the antenna switching module for each of the plurality of first switch positions.
