Description & Specification
WT-187-FAP-50 Waveguide Termination
S/C-Band Low Power Waveguide Load (WR187)
The WT-187-FAP-50 is a high-precision low power waveguide termination designed by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for multi-band S and C-band applications. Utilizing a Round Flange (FAP48) interface and the standard WR187 waveguide size, it operates seamlessly within the 3.95 GHz to 5.85 GHz frequency range. This model delivers superior low VSWR performance, making it a reliable choice for system-level dummy loads and laboratory test bench configurations. Precision machined in Taiwan, this load features standard rectangular waveguide styling with a thickness of 7mm round flange structure to optimize electromechanical alignment.
