Isolators and Circulators

Isolators and Circulators


Pasternack RF isolators are passive 2-port microwave devices that help protect

RF components excessive current or signal reflection. Our RF isolators act as a

unidirectional trap, isolating a source and load so that any reflected energy at the

load is trapped or dissipated. RF circulators from Pasternack 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.


50 Ohm RF isolators and circulators are available with SMA and N connectors only. Our broadband isolators and 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 isolators and circulators have a power rating between 10 Watts and 20 Watts and maximum VSWR of 1.45:1. Many of our RF and microwave isolators and circulators are RoHS and REACH compliant.
