SPDT PIN diode absorptive switch offers wide frequency band
A supplier of on-demand microwave and RF components, Fairview Microwave, has released an SPDT PIN Diode Absorptive Switch that offers exceptional performance across a wide range of frequencies.
The FMSW2026 is a broadband single pole double throw (SPDT) PIN diode switch that covers 100MHz to 67GHz 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 multi-point wireless transmission links and test and measurement applications.
Fairview’s FMSW2026 SPDT PIN diode switch features impressive broadband performance characteristics that 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 100nsec 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 -30o to +60o°C and uses dual voltage controls of +5 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.
“Our FMSW2026 single pole double throw absorptive switch performs across an extremely broad frequency band from 100MHz to 67GHz and offers impressive levels of performance in a compact and ruggedly built coaxial package. Designers will find this switch appealing for a multitude of RF, Microwave, and Millimeter-wave applications and can order this switch for same-day shipping from stock,” said Brian McCutcheon, Vice President and General Manager at Fairview Microwave.
