Original Abstract Submitted
Wireless circuitry can include a radio-frequency amplifier and a tunable matching network coupled to an output of the radio-frequency amplifier. The tunable matching network can include series inductors, first switches coupled between the output of the radio-frequency amplifier and a first portion of the series inductors, and second switches coupled between the first portion of the series inductors and an output port of the tunable matching network. The tunable matching network can further include an adjustable balun having a primary coil coupled to a second portion of the series inductors and having a secondary coil. The wireless circuitry can include control circuitry configured to activate and deactivate the first and second switches to operate the tunable matching network across a wide range of frequency bands.
