Description  

Matched and Cryogenic waveguide loads consist of tapered absorbers within a waveguide section. Tunable Shorts have micrometer screw to move short circuits plane and vary path length.

Standard line of ELVA-1’s matched wavegude loads ML-XX/CF/BW series provide low level of reflected power within a narrow or full waveguide band.

Cryogenic loads CL-XX/BW are to be used for absolute calibration tests: radiometers, noise souses, receivers, noise figure measurements. They can be narrow or full band as well.

The SC-XX tunable shorts ideally suit for precise adjusting of waveguide path length. Joined with circulators CR-XX/CF/BW series create tunable phase shifter PS-XX/CF/BW.

How to order

Specify Model Number ML/CL/SC— XX/CF/BW, where

XX  – number of waveguide standard (Ex. 10 for WR-10 and 06 for WR-06)

CF  – central frequency (in GHz)

BW – bandwidth (in GHz), are empty for full waveguide band

 

Examples

ML-10/94/2  - W-band matched load, WR-10, Central frequency 94GHz, Bandwidth 2GHz

All ELVA-1 waveguide loads & shorts are warranted by the manufacturer for one year after receipt.
