Abstract
Greater levels of microwave and millimeter microwave frequency power is achieved in a new power amplifier structure in which sixteen MMIC amplifiers are supported in a 4×4 row by column matrix and the output (and input) manifold is of a “crazy-H” power combining structure. Even greater output power, on the order of 100 watts at 35 GHz, is achieved by combining multiple numbers of such power amplifier units through a radial combiner.
