Abstract
Narrow band tunable radio frequency (RF) power amplifiers (PAs) and related methods are disclosed that provide narrow band tunable gain responses, such as linear gain responses, that can be selected for different frequency bands. The narrow band tunable PAs thereby provide out-of-band rejection for different selectable frequency bands so that narrow band filters are not required in the transmit input path for communication devices. The pass band location and/or bandwidth for the narrow band gain response can be tuned using different techniques, as desired. The narrow band tunable PAs can also be fabricated using CMOS processing, if desired, so that a CMOS PA integrated circuit is provided.
