Abstract
Details are given of two theoretical design for a 94-GHz ferrite circulator in a quartz substrate, based on circulation modes 1 and 2, and their predicted performances are described. The 15-dB isolation bandwidths are 8 GHz and 3 GHz, respectively. The narrower bandwidth design has a larger ferrite radius, and this may provide some mechanical advantages in manufacturing. Other comparisons are made.<>
