The MSP2TA-18D+ from Mini Circuits is an absorptive SPDT RF switch that operates from DC to 18 GHz. It can handle up to 20 W of input power, has a low insertion loss of 0.3 dB and isolation of 70 dB at 18 GHz. The switch has a switching speed of 20 milliseconds. It is available in a module and is ideal for automated test equipment (ATE) and redundancy switching for microwave radio applications.
This fail-safe switch is designed in break-before-make configuration and operates from a 24 V dc supply. Break-before-make means that it is configured to break (open) the first set of contacts before engaging (closing) the new contacts. This prevents the momentary connection of the old and new signal paths.
