A constant absolute bandwidth tunable filter using varactor-loaded open-loop resonators

2013 Asia-Pacific Microwave Conference Proceedings (APMC), 2013
This paper presents a new type of lager tuning rate tunable filters using varactor-loaded open-loop resonators. The filter is based on capacitively loaded folded λ/2 resonators that are coupled to each other with mixed electrical and magnetic coupling. By adjusting the value of the varactors between the open gaps in a mixed coupled filter, the coupling

Constant absolute bandwidth tunable filter using varactor‐loaded open‐loop resonators

Microwave and Optical Technology Letters, 2014
AbstractTwo novel cascaded microstrip open‐loop resonators with loading varactors are presented to design tunable filter. In two coupled resonators, the coupled sides can provide both electrical and magnetic coupling. A capacitance loaded at input/output feed line is used to control the external quality. By adjusting the parameters of coupling side and
