Model SWD-1040H-10-SB is a 10 dB W-band high directivity directional coupler. The directional coupler is based on traditional multi-hole coupling mechanism. The directional coupler is constructed with machined brass waveguide housings. With detailed electrical/mechanical design and precision fabrication process, the directional coupler offers instrumentation quality and superior RF performance.

The directional coupler has less than 1.0 dB insertion loss, 10 dB +/- 1 dB coupling level and 40 dB directivity cross entire 75 to 110 GHz frequency range. The couplers are also offered in other coupling level, such as 3, 6, 20, 30, 40 dB and in other frequency bands from Ka to E bands.
