Description & Specification
WR-90 End Launch Standard Gain Horn Antenna
End Launch Inline Configuration | 8.2 - 12.4 GHz | Model: HS-090-UBR-20A-E-SF
The HS-090-UBR-20A-E-SF is a high-performance End Launch Standard Gain Horn Antenna professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for the WR-90 standard. Operating within the high-frequency X-Band spectrum across the continuous 8.2 GHz to 12.4 GHz band, this premium antenna features a specialized inline coaxial-to-waveguide transition, making it ideal for linear system integration where right-angle space is limited. Delivering a stable nominal gain of 20 dBi with exceptional radiation symmetry, it features a standardized UG-39/U (UBR Style) flange mating face paired with a premium stainless steel SMA-Female interface port, ensuring flawless structural impedance coplanarity and ultra-low-loss power transfer. Safely managing continuous wave power loads up to 300 Watts (CW), this radiator is precision machined from high-grade structural aluminum alloy in Taiwan. It exhibits outstanding electromechanical longevity, a robust 380g profile, and a maximum V.S.W.R threshold of 1.25 : 1, making it the definitive choice for EMI/EMC Testing, high-fidelity antenna calibration ranges, and mission-critical Signal Integrity measurements.
