The FMSW2026 is a new, ultra broadband single pole double throw (SPDT) PIN diode switch that covers 100 MHz to 67 GHz and is available in a coaxial package. Having such a broad frequency range with low insertion loss, high isolation, and fast switching speed across RF, microwave, and millimeter-wave bands makes this switch ideally suited for a multitude of applications that include military radar, satellite and multi-gigabit communications, surveillance systems, point-to-point and point-to-multipoint wireless transmission links and test and measurement. It features impressive broadband performance characteristics that include maximum input power handling of 0.5W CW, insertion loss of 6 dB typical, 10.5 dB maximum, and isolation of 65 dB typical, 40 dB minimum. The design also displays fast switching speed of 100 nsec maximum. J1 and J2 ports are terminated in 50 ohms when switched in the isolation (off) state to absorb higher frequency signal reflections. TTL compatible driver logic circuitry is included for accurate switching control.
