Abstract

A hybrid filter may include sum, low-pass, high-pass, and intermediate nodes. A terminating impedance may couple the intermediate node to a circuit ground. A first low-pass network may couple the sum node to the low-pass node, and a first high-pass network may couple the sum node to the high-pass node. A second low-pass network may couple the high-pass node to the intermediate node. A second high-pass network may couple the low-pass node to the intermediate node. The second high-pass network may include the series connection of a first capacitor, a coupling network, and a second capacitor. The coupling network may include two coupling sections each with planar broadside-coupled first, second, and third conductor elements separated by dielectric layers. The first and third conductor elements in each section may be connected electrically in parallel.
