DIVIDER/COMBINER AMPLIFIER Abstract of the Disclosure A divider/combiner amplifier circuit divides input power through a sectored coaxial line to a plurality of longitudinal parallel channels spaced around the circumference of a cylinder; the power in each channel is amplified by a semiconductor device; and the amplified power is combined in another sectored coaxial line. A microwave waveguide connected to the input and output of each amplifying device confines the microwave energy of the operating mode to the longitudinal channel formed by said waveguide. Each waveguide extends longitudinally along the cylinder and each is circumferentially spaced from its neighboring waveguide by a space which forms a cut-off waveguide to the operating mode. In the event of a failure of one or more amplifying elements, the space allows the failure mode to propagate radially to microwave absorbing material where it is absorbed to prevent reflection back into the longitudinal waveguide and thus effectively isolates the failure to provide a gradual deterioration of the amplifier circuit performance with element failure.
