Waveguide Crossguide Coupler, 26.5 - 40 GHz (Ka-band), 30 dB Couple thru 2.92 mm
Part Number: COXD-KA30WC0
The Raytech COXD-KA30WC0 Waveguide Crossguide Coupler is engineered for precision coupling across the full Ka-band (26.5 – 40 GHz). Designed for laboratory, measurement, and system-integration environments, it delivers stable 30 dB coupling with a ±1.5 dB accuracy and excellent VSWR performance across all ports.
Constructed from aluminum alloy with space qualified chromate coating, the COXD-KA30WC0 ensures durability, low insertion loss, and consistent electrical characteristics even under demanding conditions. The coupler offers WR-28 (UG-599/U) waveguide interfaces for input and output, and a 2.92 mm (female) coaxial coupling port for reliable monitoring or power sampling.
With a minimum directivity of 15 dB and superior mechanical alignment, this model is ideal for network analysis, power monitoring, and high-frequency component testing in Ka-band systems. Optional plating and material configurations are available upon request.
