With defense and commercial applications from ground systems to airborne platforms, Logus Microwave’s model LM90BSL23 WR90 waveguide switch operates from 8.2 to 12.4 GHz. The device offers a maximum VSWR of 1.10:1, maximum insertion loss of 0.07 dB, and minimum isolation of 80 dB.

The double-pole, double-throw (DPDT) latching switch provides manual override options and is suitable for full exposure to harsh weather conditions. It supports up to four indicator circuits or inhibits, lending it application flexibility, with an option for metric or custom flanges. The switch is available with a high-logic (TTL) interface as well as with alternatives to traditional latching actuation types, including failsafe and pulse-latching options.

Logus’s LM90BSL23 waveguide switch requires 28-V DC input power and comes with a UG cover.
