Keysight 87106A/024/161: Multiport Coaxial Switch for Enhanced Signal Routing (DC-4GHz)

Keysight 87106A/024/161 – SP6T Multiport Coaxial Switch, DC to 4 GHz, Magnetic Latching.

The Keysight 87106A/024/161 is a terminated SP6T (Single Pole, 6 Throw) coaxial switch engineered to deliver exceptional isolation, low insertion loss, and outstanding repeatability in critical RF test environments. With support for DC to 4 GHz, it is optimized for integration in automated test systems (ATS), RF monitoring setups, and signal routing frameworks that demand both speed and reliability.

Thanks to its magnetic latching design and 10 million-cycle mechanical life, the 87106A ensures long-lasting operation in high-throughput environments. The included (024) 24 VDC actuation and (161) 16-pin DIP socket with 24-inch ribbon cable (bare wire) allow for seamless integration into custom or rack-mounted test systems.

For engineers and system integrators seeking low repeatability errors, the 87106A offers 0.03 dB repeatability up to 5 million cycles, reducing recalibration needs and maximizing uptime.
