Abstract

An amplifier arrangement has a plurality of function strings, which are required for nominal operation. In addition, the amplifier arrangement has a redundancy circuit and a redundant function string including a redundant converter and a redundant amplifier. If a function string is faulty, the redundancy circuit supplies the input signals of the faulty function string to the redundant function string. In addition, a high-frequency system with an inner housing and an outer housing is described, wherein an air gap separates the inner housing and the outer housing from one another so that high-frequency signals can be transmitted via the air gap between the inner housing and the outer housing.

Claims9

Dependent claims

An amplifier arrangement comprising:

a plurality of input connections;
a redundancy switching mechanism;
a converter unit;
an amplifier unit connected to the converter unit;
a redundant converter;
a redundant amplifier connected to the redundant converter;
a plurality of output connections connected to the amplifier unit and the redundant amplifier;
and
wherein each input connection is assigned a power divider, which divides an input power fed into each input connection and provides a first portion of the input power to the converter unit and provides a second portion of the input power to the redundancy switching mechanism;
and
wherein the redundancy switching mechanism is embodied to feed a signal of one of the plurality of input connections to the redundant converter selectively.
