A/B Electromechanical Relay Switches (A/B RF Relays)

Pasternack coaxial RF electromechanical relay A-B switches (A-B RF relays) are passive microwave devices that route a high frequency RF signal through a set transmission path. RF electromechanical relay A-B switches from Pasternack are most commonly used in microwave test systems for routing varying RF signals between instruments, allowing multiple tests to be performed at the same time using the same setup. Many of our electromechanical RF relay A/B switches are RoHS and REACH compliant.


50 Ohm A-B coaxial electromechanical relay switches are available with BNC and N connectors. Our 75 Ohm A-B relay switch box have BNC and type N connector options as well. Our broadband electromechanical RF relay A-B switches have frequency capabilities ranging from DC to 1 GHz depending on type and style and very low VSWR. Pasternack Enterprises’ RF electromechanical A-B relay switches have a power rating of 5 Watts and may have additional features depending on version.


The Pasternack facility certified to ISO 9001:2015 ships all coaxial RF electromechanical relay A-B switches from stock the same day you order them.
