Reconfigurable Differential Filter With Constant Absolute Bandwidth and High Common-Mode Suppression
IEEE Microwave and Wireless Components Letters, 2018A reconfigurable differential filter with constant absolute bandwidth (ABW) and high common mode (CM) suppression is proposed in this letter. The design is aiming to achieve the constant ABW under the differential mode (DM) by choosing the loading place of the varactors on the resonators and adjusting the external quality factor.

Compact Reconfigurable Dual-Band Bandpass Filter with Constant Absolute Bandwidth
2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2018 A compact dual-band bandpass filter (BPF) based on stepped impedance resonator (SIR) and defected-feeding structure is investigated in this paper. The SIR with T-stub centrally loaded provides more degrees of freedom to adjust the dual-band resonant frequencies.

VHF Discrete-Tuned Filters With Constant Insertion Loss and Absolute Bandwidth
2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2019 These instructions give you basic guidelines for preparing papers for conference proceedings. This letter presents a novel two-pole tunable bandpass filter with constant insertion loss and absolute bandwidth designed for 30-90 MHz operation. The centre frequency and inter-stage coupling are synchronously discrete-tuned by connecting PIN switched ...

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

A 0.94 ∼ 1.50 GHz Constant Absolute Bandwidth Tunable Bandpass Filter with Electric Coupling
2018 Progress in Electromagnetics Research Symposium (PIERS-Toyama), 2018In this paper, a method to get the electrically tunable bandpass filter with constant absolute bandwidth base on electric coupling is presented. By changing the position of the capacitor, the resonator can conveniently obtain the different slopes coupling line, and the constant bandwidth filter can obtain.

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
