Abstract
Reducing harmonics in a radio transmitter can involve using an electronically tunable harmonic filter (ETHF) in a transmit path at the output of an RF power amplifier stage to reduce harmonic signal components in the RF transmit signal. At least one filter characteristic of the ETHF is selectively controlled using one or more RF switch. The one or more RF switches that are used to control the ETHF can include a CMOS-SOI and/or a MEMs type of switch. Various filter characteristics of the ETHF can be controlled including a bandwidth and/or a center frequency of the ETHF.
