The WT-19-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 40.0 GHz to 60.0 GHz U-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 alloys in Taiwan, the interior architecture integrates a highly uniform absorbing element that effectively dampens extreme field waves without path distortion. Featuring a standardized circular FUGP500 Round Flange layout, this ultra-lightweight 0.055 kg component ensures perfect electromechanical concentricity and zero boundary signal leakage, safely managing continuous wave power loads up to 3 Watts (CW) and peak power surges up to 0.3 kW. Its optimized structural footprint making it the definitive choice for precision laboratory test bench configurations, system-level architecture integrations, millimeter-wave sensor testing, and mission-critical Signal Integrity diagnostics inside professional RF systems.
