The WT-15-GP-3 is a laboratory-grade millimeter-wave (mmWave) Low Power Waveguide Termination Load professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for absolute signal absorption and calibration isolation routines across the continuous 50.0 GHz to 75.0 GHz V-Band spectrum. Meticulously optimized to enforce strict impedance matching and prevent critical boundary reflections, this premium dummy load delivers an exceptionally flat and low maximum V.S.W.R profile of ≤ 1.10 : 1. Precision CNC machined from high-grade structural aluminum and copper alloys in Taiwan, the interior architecture integrates a high-homogeneity absorbing element that effectively dampens millimeter-wave energy without field or path distortion. Equipped with a standardized precision FUGP620 Round Flange interface layout, this ultra-lightweight 0.03 kg component ensures flawless electromechanical concentricity and zero boundary RF leakage, safely managing continuous wave power loads up to 3 Watts (CW) and peak power surges up to 0.1 KW. Its optimized micro-structural footprint makes it the definitive choice for next-generation 5G/6G research networks, advanced high-speed wireless backhaul development, high-bandwidth satellite communication configurations, and mission-critical Signal Integrity diagnostics inside professional test bench frameworks.
