Product Details
The HA-1840GA1-KF is a premium directional wideband radiator engineered and manufactured by FT-RF for millimeter-wave configurations and high-frequency validation systems. Operating seamlessly across the continuous 18.0 GHz to 40.0 GHz range (K and Ka bands), it delivers a consistent nominal gain of 10 dBi to 17 dBi with stable beam directivity. CNC-machined from aerospace-grade 6061 aluminum alloy with an integrated DC Short transient mitigation circuit, it safely manages up to 300 W peak / 150 W CW, protecting connected receivers and instrumentation from surge damage. Equipped with a durable stainless steel 2.92mm (K) Female interface, this compact ultra-lightweight horn minimizes insertion loss and maximizes co-polarization accuracy. A definitive reference for 5G research, automated EMC/EMI testing, anechoic chamber testing, and signal integrity compliance scanning.
