RF and Microwave Switch Platforms

Designed to shorten the custom switch development time while getting a robust, reliable solution, the Keysight L449xA products provide the switch drive control and space to mount your RF switches, attenuators and other signal conditioning components.

There are 2U and 4U versions available to give you flexibility for your unique needs and provide you with expandability for future projects. Both platforms come standard with 64 coil drives integrated into the enclosure. Distribution boards provide the right power and control signals to the switches using standard ribbon cables. Switch sequences, verification, relay counts and the graphical web interface ensure quick set-up and reduce the time for troubleshooting and repair.

This platform is ideal for R&D and manufacturing engineers creating custom switch solutions for A/D and wireless applications testing mobile radios, handsets, base stations and other radio components.
