Abstract:

In view of the K-band miniaturization power combining, this paper describes an plan by combining the waveguide power distribution and the waveguide-to-microstrip. A six-channel power distribution network is designed in this paper. By combining three-channel waveguide power divider with waveguide-to-microstrip  transition of double probes, and using software to design and optimize, the six output ports achieve good magnitude and phase consistency in 24-26 GHz。The network which has very low insertion loss and return loss is applied widely to the field of millimeter wave high power combining.
