A Low loss Power Combining Module for UTC-PD in the W Band

This paper proposes a power combining module for uni-travelling-carrier (UTC-PD) in the W-band, which is designed to be low loss. By using two paths for power combining and a single DC input port, the module is able to increase the overall output power. And this module can achieve low insertion loss, ranging from 0.24dB to 0.35dB in W band.
