Abstract
This paper shows a design of improved radial power combiner used for combining a large number of MMIC power amplifiers. We analyzed the characteristics of the MMIC power amplifiers, and developed a 16 way improved radial power combiner worked at 5-6 GHz which has the VSWRs of both input and output < 1.7, the ports imbalance of the amplitude < ±0.4, as well as the phase < ±2 degrees, a high isolations, and also has a small size of 56 mm diameter. The combiner is expected to reach an efficiency of near 90%.
