Constant absolute bandwidth tunable asymmetric order dual‐band BPF with reconfigurable bandwidth using mode control technique

Abstract Herein, a dual‐band bandpass filter with bandwidth tuning and constant bandwidth centre frequency tuning is presented, where the first and second bands are, respectively, of two and three modes. Based on λ/2 resonator modal analysis, a varactor‐ended stub is centrally loaded to a varactor‐t...
