RF Isolators

Pasternack RF isolators are passive 2-port microwave devices that help protect radio frequency components excessive current or signal reflection. Our coaxial RF isolators act as a unidirectional trap, isolating a source and load so that any reflected energy at the load is trapped or dissipated. Isolators are made of ferrite materials and magnets which determine the direction that the entering signal will flow. These RF ferrite isolators have minimum isolation ratings between 16 dB and 20 dB.


Pasternack’s 50 Ohm isolators are available with SMA and N connectors. Our broadband RF coaxial isolators 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 have a power of 20 Watts and maximum VSWR of 1.45:1. Many of our RF / microwave isolators are RoHS and REACH compliant.


The Pasternack facility certified to ISO 9001:2015 ships all ferrite RF isolators from stock the same day you order them. Pasternack Enterprises offers the broadest and deepest inventory of RF and microwave components available. Expert technical support and friendly customer service personnel are always here to assist you with coaxial isolator questions.
