Abstract

A transmit filter for a communications device includes a surface acoustic wave (SAW) band-pass filter configured to pass a transmit frequency band and a tunable transmitter impedance matching network in series. The tunable transmitter impedance matching network matches an input impedance of the SAW band-pass filter to the output impedance of a power amplifier over a portion of the transmit frequency band in response to a tuning input.
