Novel cymbal filter for dc-block and bandpass applications

Abstract

A new dc-blocking parallel-cascaded bandpass filter is presented. The filter is much easier to use and fabricate, more compact, and simpler to design than the conventional end-coupled or parallel-coupled line filters. The filter has a wide passband with a 2:1 VSWR bandwidth of around 10% and an insertion loss of about 1 dB at X-band. Simulated results agree very well with experiment results. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 33–34, 2001.
