Pasternack’s 3-port RF circulators (also referred to as RF duplexers) control the signal direction and flow inside of an RF circuit. RF circulators are unidirectional and circulate the flow of energy from each port to its clockwise adjacent port. Like RF isolators, circulators are made of ferrite materials which determine the direction that the entering signal will flow. The new circulators are designed with SMA or Type-N connectors and operate between 380 MHz to 2.2 GHz, have maximum power ratings to 1,000 Watts and have up to 20 dB isolation.

New RF isolators from Pasternack are 2-port passive devices that help protect RF components from excessive power reflection. Ferrite isolators act as a unidirectional trap, isolating the signal so that any reflected energy at the load is trapped or dissipated. Just like the circulators, Pasternack’s RF isolators are designed with SMA or Type-N connectors and operate between 380 MHz to 2.2 GHz, have max power ratings to 1,000 Watts and have up to 20 dB isolation depending on the desired configuration.
