Abstract
A radial power amplifier includes a coaxial input port and a radial power splitter. The radial power splitter includes a radial transmission line and a number of radial transmission line to microstrip transitions spaced about the radial transmission line for splitting input signal equally among a number of microstrip terminals. A like number of amplifier modules have their input terminals coupled to the microstrip terminals by intermediary coaxial transmission lines. A radial power combiner symmetrical with the radial power splitter includes a second set of microstrip terminals, one terminal being adjacent the output terminal of each amplifier module. The second set of microstrip terminals is coupled by a microstrip to radial transmission line transition to a second radial transmission line. The amplified signals from the amplifier modules converge along the second radial transmission line towards the common output port at which the amplified signal appears.
