Agilent/Keysight M9149A

The Keysight M9149A is a PXI high-density RF multiplexer for routing RF signals in automated test equipment and data acquisition systems. This 1×16 switch module delivers bi-directional signal routing across DC to 3 GHz with 50 Ω impedance, ensuring low insertion loss and VSWR for repeatable RF measurements. The module operates at 30 V switching voltage with 1 A switching current and handles up to 10 W RF power. Fast 3 msec switching speed and 40 dB isolation at 1 GHz support high-speed automated test sequences.
