Abstract
The realization of a bandpass elliptic filter which employs quasi-TEM (transverse electromagnetic) resonators at different planes coupled through small apertures is described. Bethe´s small-hole diffraction theory is used to predict the aperture couplings. An experimental filter illustrates the concept and shows that the configuration is suitable for high-temperature-superconducting thin-film implementation. An 80-MHz bandwidth elliptic filter centered at 1.1 GHz was designed according to the procedure described here.<>
