We propose a high-power millimeter-wave multiplexer which utilizes a ring resonator technology for a beam station of Microwave Rocket. The multiplexer consists of multi-staged ring resonators. The multiplexer switches and distributes RF power from the power source to several antenna elements. RF power of each port is determined by resonant condition as relation of each resonator circuit length and the RF wavelength. Theoretical analysis of the multiplexer which has 5 staged ring resonators is represented at the frequency of 170 GHz for single output port selection, equally power distribution, and Gaussian power distribution assuming active-phased-array antenna operation. By changing the circuit length of each ring resonator stage, all the operations are well represented in success. The performance of equally power distribution and Gaussian power distribution are less dependent on reflection coefficient of beam splitters of resonators. The multistaged ring resonator type multiplexer can be utilized for RF power control in the beam station of Microwave Rocket.
