DUAL-BAND BAND-PASS FILTERS AND METHOD OF USE

A filter includes shunt circuits coupled between a reference node and each of an input port, an output port, a first node, and a second node. Resonant networks are coupled between the input port and the second node, and between the first node and the output port. Storage element circuits are coupled between the input port and the first node, and between the second node and the output port. The shunt circuits have an equivalent shunt circuit frequency response that partly defines a high passband frequency of the filter, the resonant networks have an equivalent resonant network frequency response that partly defines a low passband frequency of the filter, and the storage element circuits have an equivalent storage element circuit frequency response that defines a stopband frequency of the filter between the low passband frequency and the high passband frequency. 本揭露揭示种滤波器，其包含耦合于参考节点与输入端口、输出端口、第节点及第二节点中的每者之间的分流电路。共振网络耦合于所述输入端口与所述第二节点之间，且耦合于所述第节点与所述输出端口之间。存储元件电路耦合于所述输入端口与所述第节点之间，且耦合于所述第二节点与所述输出端口之间。所述分流电路具有部分地定义所
