Tunable lumped-element bandpass filters with constant bandwidth
Lumped-element bandpass filters using LC-tanks and immittance inverters are considered. Tuning of the central frequency is provided by using variable capacitors of LC-tanks and immittance inverters. Tunability of constant-bandwidth bandpass filters is analyzed. Conditions to keep absolute and fracti...
