A high frequency amplifier for amplifying an input signal, the high frequency amplifier comprising:

• 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 termination connected with the isolated port,
• wherein the hybrid coupler circuit is connected to output sides of the first amplification circuit and the second amplification circuit,
• wherein the high frequency amplifier has an operating range based on the first amplification circuit and the second amplification circuit,
• wherein the high frequency amplifier has a load modulation in dependence of the first amplification circuit and the second amplification circuit,
• wherein a first contact of the at least one switch device of the termination is directly connected to ground, and
• wherein the ground is associated with a deheating component that is configured to deheat the at least one switch device during operation of the high frequency amplifier.
