Microstrip circulators and isolators
Microstrip circulators and isolators are passive, non-reciprocal RF/ microwave components that control signal flow direction between ports. The devices utilize a metalized ferrite substrate on a ferrous carrier.
Interconnections are typically gold wire bonds or ribbon bonds. They are compact, lightweight, and ideal for integration into RF systems, essential in radar, communications, and electronic warfare.
