In this paper a novel tunable bandpass filter based on open ended finlines is presented. Hexagonal ferrite spheres are used as resonators to cover a tuning frequency range from 39GHz to 68GHz. The measured insertion loss of the filter varies from 5.3dB to 7dB with a typical 3dB-Bandwidth between 300MHz and 400MHz. An off-resonance isolation of about 60dB is achieved although only two spheres are used. By employing finlines for the external coupling of the resonator spheres, broadband transitions to microstrip line can be designed easily, thus simplifying the integration into a planar transmission line environment. Furthermore, the use of finlines allows to cover a considerably larger operating range than the classical rectangular waveguide based coupling structures do. © 2009 IEEE.
