Abstract
The present disclosure generally relates to a high frequency amplifier, a system and a method for setting an operating state of a high frequency amplifier. The high frequency amplifier includes at least a first amplification circuit with a first frequency range, at least one second amplification circuit with a second frequency range, a hybrid coupler circuit with an isolated port, and a termination with at least one switch device. The hybrid coupler circuit is connected to output sides of the first amplification circuit and the second amplification circuit. The termination is connected with the isolated port. The high frequency amplifier has an operating range based on the first amplification circuit and the second amplification circuit. The high frequency amplifier has a load modulation in dependence of the first amplification circuit and the second amplification circuit. A first contact of the at least one switch device is directly coupled to ground.
