Datasheet: Switch Arrays

Microwave designers employ switches to turn ON selected signal paths, while providing high isolation to OFF signal paths. As the multi-function integration specialist, Microsemi-RFIS is proficient at combining various switch configurations with other high-frequency components such as antennas, filters, isolators, power splitters, limiters, and amplifiers to form custom switch arrays that route signals among multiple output ports. Harnessing our proprietary library of building-block SPNT switches (where N = 1 to 4), we have developed customized switch arrays up to SP16T in both narrowband and broadband configurations. They are available with reflective or absorptive (non-reflective) topologies and are designed with a focus on low insertion loss, high ON/OFF isolation, and fast switching speeds. Microwave and millimeter-wave switches are important signal distribution products for many mission-critical defense and homeland security programs. Applications range from portal scanners for weapons and contraband detection, to electronic beam-steering for missiles employing phased-array radar tracking, to receiver front-end protection from electronic jamming or countermeasures.
