ROD-SWITCHED TUNABLE FILTER
Document Type and Number:
WIPO Patent Application WO/2017/136973
Kind Code:
A1
Abstract:
A rod-switched tunable resonator includes a housing defining a cavity, a first rod disposed within the cavity, a second rod disposed within the cavity, and a switch connected to the first rod and to the second rod to tune the resonator to one of a plurality of frequencies by connecting or disconnecting one or both of the first and second rods to the housing. A tunable filter may be fabricated using two or more such resonators. The rod-switched tunable resonator may be a combline resonator, coaxial resonator, waveguide resonator, or dielectric resonator.
