Abstract—An X-band isolator was designed, simulated and developed for a colossal power X-ray beam emitter assembly. The developed isolator has been used to absorb reflection losses to protect the X-band magnetron source during experimental verification of emitter assembly characteristics. A finite element magnetostatic/microwave procedure is used to implement the phase control section of a 3-port isolator. This study decrees that the isolator has an operating bandwidth from 9.8-10.4GHz, manages peak power of 0.60MW, and an average power rating of 1.6KW. A minimum of 20-dB isolation with an insertion loss of less than 0.2dB over the operating frequency band was achieved. The microwave S-parameters computations fit well with the experimental data.
