ABSTRACT:
An impedance matching device is disclosed which automatically maintains h isolation between two opposite ports of a four port hybrid while the impedance of one of the other ports varies randomly. The device operates by sampling the signal at the output of the port it is desired to isolate and adjusting the impedance of the port opposite the port of randomly varying impedance in such a way as to minimize the sampled signal and thereby maintain isolation.
