Abstract

Microwave pulse compression using a waveguide cavity formed by an inductive iris and an H-plane T-junction with the auxiliary arm shorted is studied. The individual components´ equivalent circuits are used to develop a back of the envelope calculation scheme, which estimates the key design choices regarding the length of the waveguide main cavity, the iris width and the shorted arm length. The analysis is extended to cover the impact of the aforementioned design choices on the charging time and the time evolution of the cavity standing wave. Verification is obtained by comparing a pulse compressor at 1.3 GHz with a full-wave 3-D commercial software.
