ELECTRONICALLY TUNABLE MICROWAVE BANDPASS FILTER

1967
Abstract : An equivalent circuit of two orthogonal striplines coupled by a ferrite (yttrium iron garnet) sphere is derived, using the scattering matrix method. This derivation shows that a nonreciprocal phase shifter can be represented by gyrator networks. Based on this analysis, a YIG bandpass filter, electronically tunable over a very broad frequency

Integrated Synthetic Fourth-Order $Q$ -Enhanced Bandpass Filter With High Dynamic Range, Tunable Frequency, and Fractional Bandwidth Control

IEEE Journal of Solid-State Circuits, 2019
This paper demonstrates a tunable synthetic fourth-order bandpass filter (BPF) at microwave frequencies. Two parallel second-order Q-enhanced LC BPFs responses are added with the out of phase to synthesize a fourth-order BPF response.

Compact Tunable Balanced Bandpass Filter With Constant Bandwidth Based on Magnetically Coupled Resonators

IEEE Microwave and Wireless Components Letters, 2019
In this letter, a compact high-selectivity and common-mode (CM) suppression tunable balanced microstrip bandpass filter (BPF) with constant bandwidth is designed by adopting the magnetically coupled resonators with step-impedance parallel coupling ...

Multi-band tunable terahertz bandpass filter based on vanadium dioxide hybrid metamaterial

Materials Research Express, 2019
A multi-band terahertz (THz) bandpass filter based on vanadium dioxide (VO2) hybrid metamaterial is experimentally demonstrated. From bottom to top of the filter, they are 650 nm-thick high resistance silicon substrate, 100 nm-thick Silicon nitride, 125 ...

Varactor Tuned Dual-Band Bandpass Filter With Independently Tunable Band Positions

IEEE Microwave and Wireless Components Letters, 2019
A dual-band bandpass filter with different even-mode and odd-mode resonant paths is presented. The band position can be tuned independently. The basic filter structure is a stub-loaded ring resonator.

A TUNABLE COMPLEX BANDPASS FILTER WITH SWITCHABLE CAPACITORS

Электросвязь, 2020
Разработан метод расчета комплексных фильтров на переключаемых конденсаторах (ПК) по аналоговым про- тотипам. Для этого использован метод преобразования активного комплексного RC-фильтра путем замены резисторов на ПК. Рассмотрен вариант применения идентичных комплексных звеньев на инвертирующих интеграторах, позволяющий осуществлять перестройку ...

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,
