Waveguide Sliding Load

Waveguide Sliding Load suitable for waveguide calibration Purpose, low VSWR, small power, up to 110GHz. 

The WSL series waveguide sliding terminations are precision, low VSWR terminations suited to a wide variety of precision laboratory applications. They can be used for full band one-port calibration and full two-port, isolation calibration. The effect of sliding the termination can get a greater accuracy than that achieved by a fixed load. A-INFO Precision Flange(APF) is recommended for this series.
