Abstract |
Design techniques for integrated ceramic waveguide filters with N+1 controllable transmission zeros (TZ) is presented. The integrated dielectric filters offers considerable size reduction as compared to TEM resonators. The selectivity of the filters is increased by introducing N+1 TZ using resonant coupling structures and resonating discontinuities in the external resonators. Simulated results for two asymmetrical generalized Chebyshev designs having N-1 and N+1 TZ in the upper side of the passband are presented. |
