Development of Radial Waveguide Dividers with Large Number of Ports

Power division/combination is a very important function for achieving high-performance power amplification in microwave and millimeter-wave systems, allowing the use of simpler individual amplifiers to provide microwave/millimeter wave high power signals. In this paper we address the development of divider/combiners in waveguide technology for large number of ports. Radial waveguide dividers will be studied, starting from the S-parameters representing the N-port waveguide junction, and ending with the full-wave simulations. Two different designs in this technology are studied. The experimental evaluation will come from a prototype at Ku-band, fabricated and tested in order to validate the design.
