Isolators and Circulators

Isolators and Circulators


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

RF components from excessive current or signal reflection. Our RF ferrite 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 are passive 3-port microwave devices

which control the signal direction and flow inside of an RF circuit. Pasternack RF circulators are

also unidirectional, but circulate the flow of energy from each port to its clockwise adjacent port.


50 Ohm coaxial RF isolators and circulators are available with SMA and N connectors. Our broadband isolators and circulators have frequency capabilities with ranges of 1 GHz to 26.5 GHz depending on which type and style; Pasternack circulators and isolators have very low insertion loss levels. These RF isolators and circulators have a power rating between 10 Watts and 20 Watts and maximum VSWR of 1.45:1. Many of our microwave and millimeter wave isolator and circulator products are RoHS and REACH compliant.
