A New Type of Ka-Band Waveguide-Based Power-Combining Structures

摘要：

In This paper,a power-amplifier (PA) module at kaband presented using a new type of broad-band spatial powercombining system. The combiner can accommodate more monolithic microwave integrated-circuit (MMIC) PA on limited microstrip spaceInka-band waveguide.structure with good return losses,and heat can dissipated into aluminum carrier quickly.This combiner is based on a slotline-to-microstrip transition structure,which also serves as a four-way power combiner. The proposed 2×2 combining structure combined by vertical stacking inside the waveguide was analyzed and optimized by finite-element-method(FEM) simulations and experiments.This paper demonstrates the potential of the proposed power combiner for more MMIC(PA)accepted in this type of high-power amplification at millimeter wave frequencies.
