A Fourth Order Constant Absolute Bandwidth Tunable Bandpass Filter with Cross-Coupling

2019 IEEE MTT-S International Wireless Symposium (IWS), 2019
A cross-coupled tunable filter with constant absolute bandwidth (CABW) is proposed in this paper. Coupling matrix is used to calculate the coupling coefficient of the tunable filter. Varactor-loaded resonator with separate electric dominant and magnetic dominant coupling region is employed to realize the cross-coupled topology.

Design of a six-pole tunable band-pass filter with constant absolute bandwidth

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
This paper presents the design and implementation of a tunable bandpass filter with constant absolute bandwidth. Two types of coupled microstrip lines in the anti-parallel and pro-parallel formats with varactor-loaded ⋋/2 resonators are investigated to demonstrate its advanced capacity in control of the bandwidth variation. In this design, two adjacent

A Reconfigurable Fourth-order Filter With Constant Absolute Bandwidth And Four Transmission Zeros

2019 IEEE Asia-Pacific Microwave Conference (APMC), 2019
In this letter, a reconfigurable fourth-order bandpass filter with constant absolute bandwidth (ABW) and four transmission zeros is presented. The proposed filter is composed of a pair of varactor-loaded half-wavelength resonators and a pair of quarter-wavelength resonators with varactors loading at specific position.

A tunable bandpass filter with constant absolute bandwidth based on one ring resonator

Journal of Electromagnetic Waves and Applications, 2012
A miniaturized tunable bandpass filter (BPF) with constant absolute bandwidth (ABW) based on a single ring resonator is presented in this paper. The proposed BPF is composed of one ring resonator and a pair of resonators loaded with varactors. The working frequency of the BPF depends on the pair of resonators.

Design of tunable bandpass filter using PIN diode with constant absolute bandwidth

2013 Asia-Pacific Microwave Conference Proceedings (APMC), 2013
This paper presents a tunable bandpass filter (BPF) for cognitive radio applications. The proposed two-pole BPF is implemented using lumped elements and the frequency tuning is realized by PIN diodes. Due to the L-C parallel circuit J-inverter, constant absolute bandwidth is achieved.
