This extensive selection of 12 new switch models are now offered featuring broadband multi-octave frequency coverage spanning 6.5GHz to 40GHz in SPDT and optional DPDT configurations. Designs support WRD-650, WRD-750 and WRD-180 waveguide sizes. Excellent typical performance includes 2.5dB insertion loss, 80dB isolation and up to 8.5kW power handling ability. Desirable characteristics include latching self-cut-off actuators, position indictors with manual override, TTL logic, and patented motor drive with arc suppression. These wholly weatherised rugged mil-grade packages are intended for 100% humidity exposure across a -40C to +85C operating temperatures and support an environmentally-sealed quick-connect DC-control connector with mate.

“Having a comprehensive selection of broader-band, double ridge waveguide electromechanical switch designs in-stock and ready for immediate shipment is critical for RF designers who need only one module for an urgent proof-of-concept or prototype application and can’t afford to wait for several months. Typically, other suppliers require a 16 -20+ week lead time and minimum order quantities (MOQs) for these types of products,” said Tim Galla, product line manager.
