Abstract
An amplifier with switchable and tunable harmonic terminations and a variable impedance matching network is presented. The amplifier can adapt to different modes and different frequency bands of operation by appropriate switching and/or tuning of the harmonic terminations and/or the variable impedance matching network.
Claims14
An arrangement configured to receive and amplify a first signal, the arrangement comprising:
- an amplifier having an amplifier output terminal, the amplifier configured to generate a second signal by amplifying the first signal;
- two or more shunt harmonic terminations, configured to be operatively connected between the amplifier output terminal and a reference voltage, and
- one or more switches operatively connected to the two or more shunt harmonic terminations,
- wherein:
- the one or more switches are configured to selectively decouple the amplifier output terminal from the two or more shunt harmonic terminations;
- a switch of the one or more switches is configured to selectively decouple the amplifier output terminal from either one of at least one of the two or more shunt harmonic terminations, and including a configuration where the amplifier output terminal is decoupled from all of the at least two shunt harmonic terminations;
- a shunt harmonic termination of the two or more shunt harmonic terminations comprises variable elements;
- and
- each of the two or more shunt harmonic terminations is configured to resonate at a corresponding harmonic resonant frequency.
