Microwave-millimeter wave circuit apparatus and fabrication method thereof having a circulator or isolator |
摘要 |
<p>Circuits having active devices, a pattern for a circulator or isolator, and ferrite are formed on a semiconductor microwave - millimeter wave circuit substrate. The ferrite is embedded in a dielectric substrate. The dielectric substrate is oppositely aligned with the semiconductor microwave - millimeter wave circuit substrate having the pattern for the circulator or the like. Thus, the pattern is coupled with the ferrite so as to structure the circulator or isolator. <IMAGE></p> |
