Fairview Microwave SP8T Electromechanical Relay RF Switches

Fairview Microwave Single-Pole, Eight-Throw (SP8T) Electromechanical Relay RF Switches are manufactured in a SP8T design with SMA ports and a latching or normally open actuator. These coaxial electromechanical switches are rated for a maximum frequency of 18GHz and a maximum input power of 60W or 100W. Additional features include 50Ω impedance, 12V or 28V control voltage, and 125mA, 200mA, or 375mA current. Fairview Microwave SP8T Electromechanical Relay RF Switches are rated for 0.5dB or 0.6dB maximum insertion loss, 60dB or 75dB minimum isolation, and 1.6:1 maximum VSWR. These switches are suitable for test and measurement, communications, and general-purpose, high-performance applications.
