Guide To Selecting A Coaxial Switch

By Dow-Key Microwave

A coaxial switch is an electromechanical relay - a passive component - used to direct RF signals from one path to another path. This type of switch is widely used in signal routing applications where high frequency, high power, and great RF performances are required. It is commonly used in RF applications testing DUT, switching between antennas, SATCOM, Telecom, base stations, avionics, or in any other applications where RF signals need to be routed from one point to another. This tutorial will guide the user in selecting the right switch configuration for one's application to identify critical switch parameters and characteristics. It further introduces the user to all available options offered with a coaxial switch.
