Design and test of the high phase consistency six-way microwave power divider

Abstract

In this paper, a high phase consistency six-way micro-wave power splitter is presented. The proposed structure consists of coaxial line, T structure stripline and radial line and the quarter-wavelength transformor. Coupling conductor is to solve the issue of phase consistency. In the working frequency band 5.3GHz to 5.9GHz, input return loss is less than −18.3 dB, output return loss is less than −15.3 dB, phase consistency is better than ±1 degree, and insertion loss is less then 0.2 dB.
