The Keysight (Agilent) 87104R is a single-pole, four-throw (SP4T) electromechanical coaxial switch engineered for low passive intermodulation performance across DC to 26.5 GHz. This terminated switch delivers -160 dBc typical PIM, making it suitable for high-integrity signal routing in communication systems, test and measurement setups, and aerospace applications. The device guarantees 0.03 dB insertion loss repeatability and 3 million cycles per section operational life, ensuring consistent performance in demanding environments.
