ABSTRACT:
This device enables one to perform individual measurements, tests, and tuning of active elements in a circuit in which the active elements are combined using couplers. Typically, the active elements are amplifiers which are power combined using quadrature power dividers and combiners. The invention uses two additional quadrature couplers, one at the front and one at the back of the circuit. All the power is introduced into one input port of the first additional coupler. The action of the first two couplers results in power flowing through one of the active elements only. The action of the second pair of couplers results in the flow of power through one output port only. After testing, the additional couplers are removed. The invention enables the one step fabrication of components on the substrate followed by testing, rather than the more time consuming and complex separate assembly and testing of four substrates.
