AT-C10-2.8V WR-2.8 Directional Coupler – available from bq-microwave
bq-microwave now offers the AT-C10-2.8V, a WR-2.8 directional coupler from AT Microwave covering 260–400 GHz. The waveguide coupler provides 10 dB coupling with high directivity and low insertion loss – designed for test equipment and system integration in the submillimeter-wave range.
What sets the AT-C10-2.8V apart
Precise machining tolerances and high-quality plating deliver low insertion loss, good return loss and high directivity across the full WR-2.8 band.
