RF Circulators

Pasternack RF circulators are passive 3-port microwave devices which control the signal direction and flow inside of an RF circuit. RF circulators are also unidirectional, but circulate the flow of energy from each port to its clockwise adjacent port. Like isolators, circulators are made of ferrite materials and magnets which determine the direction that the entering signal will flow. These RF circulators have minimum isolation ratings between 16 dB and 20 dB.


Pasternack’s 50 Ohm RF circulators are available with SMA and N connectors only. Our broadband RF circulators have frequency capabilities ranging from 1 GHz to 26.5 GHz depending on type and style and have very low insertion loss. Pasternack Enterprises’ circulators have a power of 10 Watts and maximum VSWR of 1.45:1. Many of our RF/microwave circulators are RoHS and REACH compliant.


The Pasternack facility certified to ISO 9001:2015 ships all RF circulators from stock the same day you order them. Pasternack Enterprises offers the broadest and deepest inventory of RF and microwave components available.
