Electromechanical relay transfer switches cover frequencies from dc to 40 GHz.

Electromechanical relay transfer switches cover frequencies from dc  to 40 GHz and feature exceptional performance with low insertion loss and high isolation levels.


Product line consists of 43 unique electromechanical relay transfer switches that can be utilized for numerous applications to increase system level capabilities and help simplify the overall design approach. With two input and two output ports, these coaxial transfer switches can connect two different instruments with two devices under test. Furthermore, these RF switches can be used as “drop-out switches” for signal reversal or to bypass a component under test.

Both +12V and +28V transfer switch designs offer: 

  • latching or failsafe actuators
  • indicators
  • self-cut-off
  • TTL logic
  • suppression diodes
  • insertion loss as low as 0.2 dB min
  • isolation greater than 80 dB.
  • some models feature power handling capability up to 700 Watts (CW) at 1 GHz
  • many units are RoHS and Reach compliant
  • compact and ruggedly built package outlines supporting SMA, N-Type, TNC, or 2.92-mm connectors
