AO Microwave has added ferrite waveguide circulators to its millimeter-wave passive component portfolio. The 3-port circulators provide port-to-port isolation and low insertion loss for radar, satellite communications, and 5G infrastructure. Units cover standard WR waveguide bands and are built with precision-machined housings to maintain signal integrity in high-power RF paths. The circulators suit aerospace, defense, and telecom system integrators that need reliable signal routing between transmitter and receiver chains. OEM and custom frequency configurations are available.
