Tunable bandpass passive digital filter design

The 2002 45th Midwest Symposium on Circuits and Systems, 2002. MWSCAS-2002., 2003
Sharp-cutoff filtering characteristics require a high-order filter. For a not-too-high filter order, IIR digital filters are required. In this paper, we present two methods for designing high-order tunable bandpass passive digital filters that can provide sharp-cutoff capability for real-time filtering applications.

A New Miniaturized Electronically Tunable Bandpass Filter

2006 7th International Symposium on Antennas, Propagation & EM Theory, 2006
In this paper a new electronically tunable band pass filter using coupled ring resonator is described. This filter can tune frequency ranges from 2 GHz to 4 GHz. In comparison with designed filter by Y.H.SHu the size of this filter reduced about 69% with the same frequency performance.

Progress of a tunable active bandpass filter

Annales Des Télécommunications, 1992
A review of a tunable active bandpass filter developed in our research group is given here. Presented first is the basic structure of an end-coupled microstrip-line bandpass filter. Next discussed is the concept of using coupled negative resistance to compensate the loss of tank circuit.

Mechanically tunable coupled resonator waveguide bandpass filter

2019 IEEE Microwave Theory and Techniques in Wireless Communications (MTTW), 2019
This paper proposes a novel mechanically tunable waveguide filter design, based on a coupled resonator topology. The resonator geometry consists of a rectangular waveguide cavity and a dielectric cylinder. Unlike conventional cylindrical resonators which are made out of a single part, here the cylinders are cut in half. By changing the distance between

FREQUENCY-TUNABLE MICROWAVE BANDPASS FILTER

2011
The invention relates to a frequency-tunable microwave bandpass filter that comprises, altogether, at least the following elements: a wave guide having a rectangular cross-section and including a stationary first conductive portion I and a movable second conductive portion II. Said first portion includes a plurality of first conductive partitions (1051,
