Narrow-band tunable radio frequency (RF) power amplifiers and related methods

A narrow band tunable radio frequency (RF) power amplifier, comprising:

• amplifier circuitry configured to receive a radio frequency (RF) signal and to generate an amplified RF output signal, the amplifier circuitry configured to provide a narrow band gain response tunable across a plurality of different frequency bands based upon one or more tuning control signals, and the narrow band gain response being linear across the different frequency bands;
• and
• control circuitry configured to provide the one or more tuning control signals to the amplifier circuitry based upon a frequency band selection signal;
• wherein each of the plurality of different frequency bands are associated with a different communication system;
• wherein the narrow band gain response is configured to pass frequencies within a selected frequency band and to reject frequencies outside the selected frequency band;
• and
• wherein the amplifier circuitry and the control circuitry are integrated on the same integrated circuit.
