LIQUID LOAD Russian patent published in 2005 - IPC

FIELD: microwave engineering; terminal loads of heavy-power waveguide channels.

SUBSTANCE: proposed liquid load characterized in reduced dependence of load matching on permissible power level at coolant temperature varying between -60 and +110 ^oC has rectangular waveguide section and insulating insert passed through its inner cavity filled with flowing absorbing liquid. Insulating insert is disposed inside case connected to rectangular waveguide section provided with coupling window. Inner cavity of insulating insert accommodates metal tube with hole and reflector secured in immediate proximity of hole. Piston is mounted downstream of insulating insert inside rectangular waveguide section.

EFFECT: reduced dependence between load matching and increase in permissible power level due to coolant temperature variations.
