A Study on the Simple-loop Hybrid Ring（Part l） 　?Simple-loop Hybrid Ring with unequal Output Power Ratio?

摘要

The simple-loop hybrid ring has a simple structure but its electrical characteristics arenu27t too much better than other hybrid rings. By terminating with the image immittance and making the output power ratio unequal at the center frequency，the frequency characteristics of the simple-loop hybrid ring become broadbaded
