Abstract
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° 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
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° 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.
Claim 2
Dependent Claim
126 words
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° 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.
Claim 3
Dependent Claim
59 words
A circuit arrangement as defined in claim 1 wherein said means for controlling includes: first and second means for monitoring the output power of a respective one of said pair of amplifiers or generators; and first and second operating voltage regulator means, controlled by said first and second monitoring means, respectively, for regulating the associated said operating voltage supply.
Claim 4
Dependent Claim
65 words
A circuit arrangement as defined in claim 1 wherein said means for controlling includes: first and second means for monitoring said input resistance value of a respective one of said two decoupled inputs; and first and second operating voltage regulator means, controlled by the monitored said input resistance value from said first and second monitoring means respectively, for regulating the associated said operating voltage supply.
Claim 5
Dependent Claim
39 words
A circuit arrangement as defined in claim 2 wherein each of said monitoring means is a directional coupler connected between the output of one of said amplifiers or generators and the associated input of said 90° parallel circuit bridge.
Claim 6
Dependent Claim
39 words
A circuit arrangement as defined in claim 3 wherein each of said monitoring means is a directional coupler connected between the output of one of said amplifiers or generators and the associated input of said 90° parallel circuit bridge.
Claim 7
Dependent Claim
40 words
A circuit arrangement as defined in claim 5 wherein: each of said first and second regulating means regulates the associated operating voltage supply substantially proportionately to the square root of the associated input resistance value of said parallel circuit bridge.
Claim 8
Dependent Claim
36 words
A circuit arrangement as defined in claim 1 wherein the element of the amplifier whose operating voltage is regulated upwardly has a maximum permissible operating voltage which lies at the upper limit of the regulating range.
Claim 9
Dependent Claim
30 words
A circuit arrangement as defined in claim 1 wherein the element of the amplifier whose operating voltage is regulated downwardly has a sufficient reserve with respect to the permissible current.
