kTB Solutions Waveguide Switches NWSD-42

The NWSD-42 is a DPDT waveguide switch designed for operation from 18 to 26.5 GHz with WR-42 interfaces. It features a maximum insertion loss of 0.1 dB, a maximum VSWR of 1.1, and minimum isolation of 60 dB. The device operates on 24 ± 2 VDC with a current draw of 1.2 A and has a switching time of 50 ms. Mechanical life is rated at 0.1 million cycles. Operating temperature ranges from -40 to +85 °C, with an extended range of -55 to +85 °C. The switch includes indicator outputs and is controlled via TTL logic with pin assignments for D-E and F-E connections to indicate position. The case is defined by the WR-42 waveguide interface with ±0.2 mm dimensional tolerance.
