Compact Microwave and Millimeter-Wave Bandpass Filters Using LTCC-based Hybrid Lumped and Distributed Resonators
2019
IEEE Access
Preserved Fulltext
By effectively merging the lumped elements and distributed effects, a modified LTCC-based hybrid lumped and distributed resonator (HLDR) is introduced. ...
The distributed part, saying, the mutual couplings between adjacent HLDRs and to the ground, is used to improve the design flexibility and filtering performance for HLDR filters. ...
Therefore, the design flexibility of lumped filters is limited by number of lumped elements. ...
