Abstract
A circuit arrangement for combining high frequency power components with the same frequency which come from amplifiers or generators and are fed to a 90.degree. parallel circuit bridge having two substantially decoupled inputs with the input resistance values of these inputs depending on the output load. The operating voltage supplies of the amplifiers or generators are separately controllable and are controlled so that the output powers of these amplifiers or generators, respectively, remain substantially constant even with mismatching.
Claims8
In a circuit arrangement for combining high frequency power components with the same frequency including a pair of amplifiers or generators for providing high frequency power components with the same frequency at their respective outputs, a 90.degree. parallel circuit bridge having its output connected to a load and two substantially decoupled inputs, each of which is coupled to the output of a respective one of said pair of amplifiers or generators with the input resistance values of said inputs depending on said output load;
- the improvement comprising:
- a separately controlled operating voltage supply for each of said amplifiers or generators;
- and means for controlling said operating voltage supplies so that the output power of each of said amplifiers or generators remain substantially constant even with mismatching.
