The Keysight L7104B is an electro-mechanical multiport coaxial switch engineered for RF and microwave signal routing across DC to 20 GHz. Built in a Single Pole Four Throw (SP4T) configuration with terminated ports, it delivers the insertion loss repeatability and isolation performance demanded in precision test systems.
Insertion loss repeatability of 0.03 dB is warranted for 2 million cycles, directly reducing measurement uncertainty in critical applications. Typical isolation reaches 90 dB at 12 GHz and exceeds 85 dB at 26.5 GHz. The switch operates reliably through 5 million cycles, with a warranted operating life of 2 million cycles.
