A tunable ferrimagnetic resonator containing microwave filter with a plural piece housing is described. First and second body laminations are provided with channels and openings which form passageways and resonator receiving cavities when the laminations are assembled. These passageways and openings are preferably formed by chemical milling. Closure elements or shims overlay and close the ends of the resonator cavities. The body laminations and closure elements are of a nonmagnetic metal and are typically formed from flat thin sheets of material. Cover laminations, such as of plastic, clamp the closure and body laminations together and provide strength to the overall housing structure. Microwave filters of this invention are capable of being tuned up to 40 Gigahertz and higher.
