The WT-137-FDP-50 is a laboratory-grade microwave 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 5.85 GHz to 8.20 GHz C and X-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 ≤ 1.05 : 1. Precision CNC machined from high-grade structural alloys in Taiwan, the interior architecture integrates a high-homogeneity absorbing element that effectively dampens microwave energy without field or path distortion. Equipped with a standardized precision FDP70 Square Flange interface layout, this lightweight 0.16 kg component ensures flawless electromechanical concentricity and zero boundary RF leakage, safely managing continuous wave power loads from 10 Watts to 50 Watts (CW) with excellent thermal dissipation. Its optimized structural footprint makes it the definitive choice for general-purpose system-level applications, high-frequency radar development, system-level architecture integrations, and mission-critical Signal Integrity diagnostics inside professional laboratory test bench configurations.
