Abstract

Quasi-optical spatial power combining provides the high combining efficiency required of solid-state power amplifiers for millimeter-wave frequencies. Photonic crystals (PXT's) are used to implement this type of power combining, as shown by two examples in this paper. The first example describes an alldielectric structure that provides a carrier for the amplifier array chip satisfying the requirements concerning unilateral transmission and thermal management. The second example describes the use of a high impedance ground plane, based on PXT's, to make the power density incident on the array chip as uniform as possible in order to maximize power and efficiency.
