Design and Realization of Chebyshev Bandstop Filters Based on Ceramic Resonators [PDF]

open access: yesAdvances in Radio Science, 2021
Distributed bandpass or band-reject filters generally become larger as the design center frequency decreases. To achieve suitable filters with small dimensions even at center frequencies below 2 GHz, ceramic resonators can be used.

Monolithic integrated ceramic waveguide filters [PDF]

open access: yes2014 IEEE MTT-S International Microwave Symposium (IMS2014), 2014
Design techniques for a new class of integrated monolithic high permittivity ceramic waveguide filters are presented. These filters enable a size reduction of 50% compared to air-filled TEM filters with the same unloaded Q-Factor. Designs for both chebyshev and asymmetric generalized chebyshev filter are presented, with experimental results for an 1800
