Fairview launches wideband SPDT PIN diode absorptive switch

Fairview Microwave Inc of Allen, TX, USA, which supplies on-demand microwave and RF components, has launched the FMSW2026 ultra-broadband single-pole double-throw (SPDT) PIN diode absorptive switch, which is available in a coaxial package and operates across a wide range of frequencies from 100MHz to 67GHz.

Broadband performance characteristics include maximum input power handling of 0.5W (CW), insertion loss of 6dB typical, 10.5dB maximum, and isolation of 65dB typical, 40dB minimum. The design also displays fast switching speed of 100ns maximum. J1 and J2 ports are terminated in 50Ω when switched in the isolation (off) state to absorb higher-frequency signal reflections. TTL-compatible driver logic circuitry is included for accurate switching control. The design features an operational temperature range of -30oC to +60oC and uses dual voltage controls of +5Vdc and -5Vdc. The compact and rugged MIL-grade coaxial package design is gold plated and has interface connections that include 1.85 female connectors for mm-wave transmission, solder terminals for DC voltages, and an SMA female connector for TTL logic control.

Having such a broad frequency range with low insertion loss, high isolation and fast switching speed across RF, microwave, and millimeter-wave bands makes the switch suitable for military radar, satellite and multi-gigabit communications, surveillance systems, point-to-point and point-to-multi-point wireless transmission links and test & measurement applications, says the firm.

The FMSW2026 SPDT PIN diode switch is in-stock and ready to ship now.
