Abstract
A microwave filter (30) and method of fabrication in which an integral housing (22) defining a cavity (23) is formed from a blank (20) cut from a conductive sheet. The blank is bent to form the housing. The resultant housing includes resonators, resonator taps, tuning holes and tap apertures. Capacitance tabs and coupling tabs are added to the housing for tuning of the filter. The tabs are adjusted by access through the tuning holes in the blank. The blank further defines stops which align the taps with lines of a microstrip circuit when the filter is installed therein and grounding tabs for grounding to the microstrip ground plane. The filter may be in combline or interdigital configuration.
