Description & Specification
33 GHz to 50 GHz Q-Band Waveguide Input Horn Antenna
Model: WI-22-UG-20 | WR-22 Waveguide | 20 dBi Gain
The WI-22-UG-20 is a high-precision Waveguide Input Horn Antenna specifically engineered for millimeter-wave RF measurements in the 33 GHz to 50 GHz (Q-Band) frequency range[cite: 234, 270]. Featuring a standard WR-22 waveguide interface and a UG flange, it delivers a stable nominal gain of 20 dBi with symmetrical radiation patterns[cite: 234, 236, 266]. This antenna is an essential calibration instrument for high-frequency Signal Integrity verification and professional laboratory setups requiring industrial-grade reliability[cite: 256].
