High-Order Planar Bandpass Filters With Electronically-Reconfigurable Passband Width and Flatness Based on Adaptive Multi-Resonator Cascades
A class of quasi-elliptic-type planar bandpass filters (BPFs) with electronically controllable bandwidth between narrow-band and ultra-wideband states and enhanced passband flatness is reported. It consists of the in-series cascade of replicas of an adaptive BPF stage that exhibits three in-band pol...
