  • Dielectric resonator filter having reduced spurious modes
    Patent number: 6239673
    Abstract: A dielectric resonator filter operating in a magnetic dipole mode includes a plurality of dielectric resonators disposed in a plurality of dielectric resonator cavities. A plurality of coupling mechanism provide an in-line coupling factor between respective resonators of electrically adjacent dielectric resonator cavities. At least one cross-coupling device provides cross-coupling between respective resonators of non-adjacent dielectric resonator cavities. A magnitude and sign of the in-line coupling factors and the cross-coupling factor, provide a dielectric resonator filter, for which a desired amplitude and phase response can be provided.
    Type: Grant
    Filed: September 23, 1999
    Date of Patent: May 29, 2001
    Assignee: Bartley Machines & Manufacturing

  • Apparatus and method for forming a housing assembly
    Patent number: 6037541
    Abstract: An apparatus and method for forming a housing assembly. The assembly comprises a first part with protrusions spaced along at least one surface which fit into through-holes in a second part and which may, when the parts are placed together, be peened such that the protrusions fill the through-holes and join the parts. The method comprises fabricating a first part with protrusions and a second part with through-holes, joining the parts together such that the protrusions mate with the through-holes, and peening the protrusions such that they fill the through-holes and join the parts.
