Abstract
A power amplifier uses a plurality of solid-state amplifiers (FIGS. 2 and 3, 140) arranged in a parallel manner to form a power amplifier module (10). Each solid-state amplifier is adhered to a low thermal expansion insert (130). The insert is then coupled to a low cost aluminum substrate in order to carry the excess heat from each solid-state amplifier (140) to the aluminum housing. The power outputs from the solid-state amplifiers from each module are combined with the power outputs from other modules using electroformed waveguide combiners (FIG. 1, 30, 40).
