DEVICE FOR SPLITTING AND RECORDING OF DIRECT AND REFLECTED MICROWAVE POWER IN QUASI-OPTICAL PATHWAY Russian patent published in 2015 - IPC G01R27/00 

FIELD: electricity.

SUBSTANCE: invention is intended for device for splitting and recording of direct and reflected microwave power in quasi-optical reflecting pathway of high power (1-500kW) at microwave pulse duration of 1-100ms and frequency range of 30-80GHz. The device comprises a body with cylinders mounted at bottom and top walls and beam divider mounted inside the body. At that walls of the body are covered with layers of profiled absorber and inside cylinders there are collimators of profiled absorber. At the end of each collimator there are detector heads, each of them consisting of waveguide corresponding to operating frequency and detector with diaphragm set opposite it. Additional cone-shaped absorber is placed in front of the waveguide and at tip of the absorber there is an opening that may be used for changing diameter and polarising grid is placed in front of input diaphragm of direct power recorder.

EFFECT: potential measurement and determination of power balance for power coming to the load, reflected load, determination of frequency content for reflected radiation at suppression of background signals.
