Description & Specification
4 GHz to 40 GHz K-Female Double Ridged Broadband Waveguide Horn Antenna
Ultra-High Frequency | Precision Design | Model: HA-0440GA-KF
The HA-0440GA-KF is a high-performance Double Ridged Broadband Waveguide Horn Antenna professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for ultra-high frequency professional microwave and millimeter-wave validation. Operating across a massive frequency spectrum spanning the continuous 4 GHz to 40 GHz range, this laboratory-grade antenna provides stable directional gain profiling from 5 to 12 dBi. Precision-machined with optimized inner double ridges, its physical geometry minimizes boundary reflections and guarantees superior radiation directivity with exceptionally low transmission loss. Equipped with a high-precision 2.92mm K-Female coaxial interface connector, this ultra-lightweight 80g antenna safely handles up to 15 Watts of continuous wave (CW) input power and 120 Watts peak power. It stands as an essential reference standard for advanced 5G wireless network testing, millimeter-wave radar development, high-frequency anechoic chamber testing, and comprehensive EMC/EMI compliance sweeps requiring high reliability and accurate repeatable radiation patterns.
