Title    The design and simulation of millimeter waveguide power combiner                                   

Abstract Power combiner is a traditional and important technology in the field of microwave,and it is still in the process of evolving. From the view of application, a single power combining amplifier unit is often difficult to meet the system requirement, so the power synthesis technology has been one of important technology ways to develop the power combiner.

This thesis is to study wideband power combiner network in the millimeter wave band, according to the software simulation and layout design and the N-way wilkinson power allocation principles.

This thesis has completed a four channel power combiner circuit with high efficiency, it works during the 28-32GHz, the magnitude and phase coherence must be very good, and the loss is less than 0.5dB, and every port should have sufficient isolation (greater than 20dB), so that the amplifiers will not interfere each other.We use our expertise to determine the overall realization of the program and complete the circuit design, layout design and simulation.
