Keysight / Agilent / HP 87222-60015 Coaxial Transfer Switch

The Keysight/Agilent/HP 87222-60015 is a coaxial transfer switch engineered for high-frequency signal routing in automated test and measurement systems. Operating across DC to 50 GHz, this transfer switch delivers exceptional insertion loss repeatability of 0.03 dB typical and high isolation performance, making it ideal for precision signal control applications requiring minimal measurement uncertainty. The device switches between two inputs and two outputs using break-before-make logic with a maximum switching speed of 15 ms. Designed for extended operational life exceeding 10 million cycles, the 87222-60015 reduces maintenance overhead and maximizes system uptime in production testing, satellite applications, antenna monitoring, and signal conditioning systems.
