Abstract

A compact 140GHz 8-way power combing module is described using compositing integrated structure. For a unit of radial power combing, the width of the module subjects to severe limitations. We develop a step-by-step design procedure, including waveguide T-junction, hybrid based on waveguide directional coupler and distorted T-junction. For purpose of improving the gain of the module, a driving amplifier is integrated. A waveguide-to-microstrip transition of coplanar waveguide (CPW) is used for feed-in microwave monolithic integrated circuit (MMIC) based on SiGe BiCMOS technology. The proposed module achieves high efficiency of 85% in 130GHz~150GHz, which is excellent agreement with measurement. It is easier fabricated and suitable for high power combing.
