Coaxial Switches & Relays

RF Coaxial Switches are electromechanical coaxial devices with multiple ports: SPDT (Single-Pole, Double-Throw), DPDT, DP3T, or SPnT (Single-Pole, Multi-Throw). Options include guaranteed operation up to 10 million cycles, frequency to 67 GHz, low PIM, and TVAC/Space options. RF & Microwave Relays are typically surface mountable or through-hole on a PCB, and can be ultraminiature, hermetically sealed, etc. Coaxial Switches and Relays provide precise and fast switching capabilities for Automated Test Equipment, high-performance military and aviation vehicles, to digital throughput requirements of complex digital signal processing and data acquisition systems. Richardson RFPD supports all types of RF Coaxial Switches & Relays from industry leading manufacturers.
