摘要：

In this article, two high selectivity balanced filters with multiple transmission zeros using ring resonators are proposed. Four, and six transmission zeros are easily realized to improve the differential mode passband selectivity and common mode suppression. Over five octaves common mode suppression can be realized by the bandstop performance of the coupled lines and stubs. Two balanced filters with 3-dB bandwidths of 23.6 and 23.5% are designed and measured. Good agreement can be found between the theoretical and measured results.
