Stamped metal interdigital bandpass rf filter

Abstract

A bandpass filter can be configured, which includes a filter structure that includes a filter chamber and a group of tuned elements including first tuned elements and last tuned elements, wherein the first tuned elements and the last tuned elements include a pin that joins a connection medium to connect to a radio frequency (RF) signal path. An outer perimeter can connect to a ground plane present on the connection medium. The ground plane can form a bottom of the filter chamber. The group of tuned elements can be folded into a shape that occupies a space midway between a top lid and the ground plane. Alternatively, the group of tuned elements can be located above the ground plane on a single side of the filter structure.
