Description & Specification
WR90 8.2 to 12.4GHz N-Female Ridge Short Circuit Waveguide Adapter
X-Band High-Power Transition | Flange: UBR Type: H1 | Model: WC-090-UBR-H1-NF
The WC-090-UBR-H1-NF is a high-power X-band ridge short circuit rectangular waveguide to coaxial adapter professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) in Taiwan. Operating across the 8.2 GHz to 12.4 GHz frequency range, it provides a high-reliability transition between standard WR-90 (WG16 / R100) rectangular waveguides and 50-ohm N-Female coaxial interfaces. Designed with an internal ridge short circuit structure, it achieves an insertion loss of only 0.15 dB and a maximum VSWR of 1.25:1. Featuring a robust aluminum alloy body with an integrated square UBR flange (compatible with UBR100 / FBP100 patterns) and a durable stainless steel N-Female connector, it handles high power levels up to 300W CW / 3 kW Peak, providing an essential solution for high-power transmitters, radar systems, and laboratory RF testing.
