The Keysight P9402C is a PIN diode solid-state switch delivering single-pole, double-throw (SPDT) performance across 100 MHz to 18 GHz. Built with individual control switch IC and discrete shunt PIN diodes, it provides three switching states: common to port 1, common to port 2, or all ports terminated at 50 Ohm. The architecture ensures superior isolation and insertion loss performance with excellent port matching in all states.
