Keysight 34947A Triple 1×2 SPDT Unterminated Microwave Switch Module

The Keysight 34947A Triple 1×2 SPDT Microwave Switch Module adds high-frequency signal routing to the Keysight 34980A Multifunction Switch/Measure Unit. Featuring three independent single-pole, double-throw (SPDT) unterminated microwave switches, the module supports RF and microwave frequencies up to 26.5 GHz, making it suitable for advanced test setups in wireless communications, aerospace, defense, and high-speed digital applications.

Its unterminated configuration offers maximum flexibility for signal routing in systems where external terminations are managed separately. The module is optimized for excellent performance, with low insertion loss, high isolation, and dependable repeatability over long operating lifetimes. By integrating microwave switching directly into the 34980A platform, it reduces external cabling complexity and simplifies system-level control.
