FIELD: physics; radio. ^ SUBSTANCE: microwave power summation device relates to microwave engineering and can be used in radio transmission devices of radio systems. The device has a K-channel divider and an adder, K M-channel dividers and adders and N amplifiers, where N=KùM. In the decimetre wavelength range K- and M-channel dividers and adders are made in form of stripline directional couplers placed in series with possibility of regulating coupling coefficients. In the centimetre wavelength range, K-channel dividers and the adder are made with F-steps using regulated double waveguide-coaxial E tee-junctions. M-channel dividers and adders are made in form of waveguide-stripline directional couplers placed in series with possibility of regulating coupling coefficients. ^ EFFECT: increased efficiency of the device due to possibility of regulating power division and regulating coupling coefficients, reduced weight and size. ^ 2 cl, 8 dwg |
