摘要

提出了一种宽频带间隔的多层双频双模带通滤波器，采用两个独立的方环谐振器。为了改善阻带特性，抑制了低频谐振器的伪二次谐波通带。通频带以3 GHz和9.35 GHz为中心，用于双频海事雷达。仿真结果与实测结果吻合较好。

A multilayer dual-band filter using dual-mode resonators with second harmonic suppression

A multilayer dual-band dual-mode bandpass filter with widely spaced passbands and using two independent square loop resonators is proposed. For improved stopband characteristics, the spurious second harmonic passband of the low frequency resonator is suppressed. The passbands are centered around 3 GHz and 9.35 GHz for application in a dual-frequency maritime radar. The simulated and measured results show good agreement.
