Patent ID: 8599726

Claim:
A radio front module comprises: a power amplifier operably coupled to amplify an up-converted signal into an outbound wireless signal; a duplexer operably coupled to an antenna and configured to provide electrical isolation between the outbound wireless signal and an inbound wireless signal; and a tunable balancing network operably coupled to the duplexer and configured to establish an impedance that substantially matches an impedance of the antenna, wherein the tunable balancing network includes an impedance up-conversion module that further includes: a plurality of capacitive elements; a plurality of resistive elements; and a plurality of low-voltage switching elements configured to, and in accordance with a tuning signal, couple one or more of the plurality of capacitive elements and one or more of the plurality of resistive elements to the duplexer as an impedance balancing load wherein the impedance up-conversion module is configured to up-covert a baseband impedance to a radio frequency impedance based upon a received clock.
