Coaxial RF Circulators

Pasternack Coaxial RF Circulators are passive 3-port microwave devices that control the signal direction and flow inside an RF circuit. These circulators allow two different direction signals to share the same channel. The coaxial RF circulators feature excellent insertion loss, high isolation, and reliability. These circulators provide a power rating ranging from 10W to 100W and a maximum VSWR of 1.45:1. The coaxial RF circulators offer minimum isolation ratings of 16dB to 20dB, with an SMA female connector interface type. These circulators are available in RoHS and REACH compliant designs for reliable performance in demanding applications. Typical applications include radar systems, military, wireless, radio systems, telecom infrastructure, and communication systems.
