Matched & Cryogenic Waveguide Loads, Tunable Shorts
Note to graphs: VSWR is 1.07 max. This is at least 30 dB of reflected power suppression.
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
ML-10/94/2 – W-band matched load, WR-10, Central frequency 94 GHz, Bandwidth 2 GHz
All ELVA-1 waveguide loads & shorts are warranted by the manufacturer for one year after receipt.
