Abstract
Radio frequency communication systems with a combined antenna impedance tuning and antenna multiplexing functionality are provided. In certain embodiments, a packaged radio frequency module includes an antenna multiplexer and an antenna impedance tuner. The module can be configured to provide impedance matching between one or more radio frequency front end modules and an antenna. The antenna impedance tuner can supplement antenna tuning provided by an antenna aperture separately connected to the antenna.

A radio frequency module, comprising:
- first and second signal ports;
- an antenna signal port;
- first and second impedance tuners, the first impedance tuner configured to provide adjustable impedance matching between a radio frequency antenna and a first power amplifier, the second impedance tuner configured to provide adjustable impedance matching between the radio frequency antenna and a second power amplifier;
