Abstract
Design of small-size tunable bandpass filters on coupled LC-tanks with variable capacitors is considered. Conditions to keep the absolute bandwidth (ABW) and fractional bandwidth (FBW) constant as well as tunability constraints are analyzed. Designs of the three-pole varactor-tuned bandpass filters with constant ABW and FWB are presented.
