Design and Evaluation of a High Selectivity Combline Bandpass Filter

Quasi-planar combline bandpass filters have been realized in suspended substrate stripline. The coupling between non-adjacent resonators and the composite effect of N quasi-TEM modes excited from N-coupled lines are considered. The design approach is b...

Advances in MIC and MMIC technology have motivated the demand for compact, high performance filters, diplexers and multiplexers used in microwave receiver systems. Combline bandpass filters have been in great demand because of their structural compactness and excellent wide stop-band performance. They are easy to fabricate in printed circuit...
