FMSW2026 SPDT PIN Diode Absorptive Switch. Source: Fairview Microwave. Fairview Microwave Inc., a supplier of on-demand microwave and RF components, has released a SPDT PIN Diode Absorptive Switch that offers high performance across a wide range of frequencies. The FMSW2026 is an 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, such as 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.
The switch features broadband performance characteristics that include maximum input power handling of 0.5 watts (CW); insertion loss of 6 dB typical and 10.5 dB maximum; and isolation of 65 dB typical and 40 dB minimum. The design also displays a fast switching speed of 100 nsec maximum. The J1 and J2 ports are terminated in 50 ohms when switched in the isolation (off) state to absorb higher frequency signal reflections. Also TTL-compatible driver logic circuitry is included for accurate switching control.
The design features an operational temperature range of -30° C to +60° C, and uses dual-voltage controls of +5 Vdc and -5Vdc. The compact and rugged MIL-grade coaxial package design is gold plated and has interface connections that include female connectors for mm-wave transmission, solder terminals for DC voltages, and an SMA female connector for TTL logic control.
The PIN diode switch is in stock and ready to ship now.
