Waveguide Load

Waveguide Low Power Load Series (WR15 to WR430)

FT-RF Waveguide Low Power Loads are precision termination solutions designed for critical microwave testing and system applications. Covering a broad spectrum of waveguide sizes from WR15 to WR430, this series supports power handling from 0.25W to 50W with an industry-leading maximum VSWR of 1.05. Each unit is engineered to ensure superior Signal Integrity by effectively absorbing RF energy and minimizing reflections.
