A variable attenuator is needed for the reduction of available microwave power, e.g. in order to bring the detector into the quadratic characteristics range. For this an attenuation vane is arranged along the axis of the waveguide, parallel to the electric field, and is adjusted using a micrometer screw.
Design:
Waveguide constructed of aluminium with LD quick connectors. Backlash-free mechanical design with micrometer. The principle attenuation curve is depicted on the housing.
- Attenuation: 20 dB (ca.)
- Calibration: 3 dB and 10 dB for 9.40 GHz
- Waveguide type: R100
- Length: 120 mm
- Weight: 650 g
