Design and Analysis of the Channel Waveguide Transformer

Abstract

The authors describe an easily fabricated H-plane transformer for use in rectangular waveguide carrying the dominant mode. An approximate theoretical analysis of the structure is presented, and computed results are compared with measurements on transformers at X-band. Design curves are given for transitions from full to one-haff, one-third, and one-quarter height waveguide. The new transformers have been found particularly useful for millimeter-wave mixers and multipliers employing split-block construction. The structure can also be used as a transition from rectangular to channel waveguide.
