  • Publication number: 20230103586
    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.

  • Patent number: 9276528
    Abstract: An amplifier includes a coupler, a main amplifier, and an auxiliary amplifier. The main amplifier and the auxiliary amplifier are supplied with signals derived from at least one input signal and amplify these. The coupler combines output signals of the main amplifier and of the auxiliary amplifier. The main amplifier and/or the auxiliary amplifier comprises an operating point adjustable during operation.

  • Patent number: 9137919
    Abstract: An inverter includes an upper and lower housing part and electronic components arranged in the upper and lower housing parts. The components are electrically connected to one another in a releasable manner by means of a contact-making system formed from two parts. In order to produce an electrical and mechanical connection by means of a pivoting movement, the upper housing part is connected to the lower housing part in a manually detachable manner by means of a rotating element which forms an axis of rotation for a circle arc. In the upper and lower housing parts, a part of the contact-making system is respectively arranged along the circle arc in such a way that these parts, during a pivoting movement of the upper housing part relative to the lower housing part into an operating position, can be automatically electrically-connected, with the housing parts connected.
