Band-Pass filters using OSRR cells

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2015
This paper presents the design process (including optimization and characterization) of a band-pass filter through the use of OSRR-structured meta-material cells over micro-strip substrates.

Optimisation‐based design of transversal signal‐interference microwave bandpass and lowpass filters with extended stopband

open access: yesIET Microwaves, Antennas & Propagation, 2021
Generalised bi‐path stepped‐impedance‐line signal‐interference bandpass and lowpass transversal filtering sections (TFSs) with increased stopband bandwidth above the main transmission band are presented.

Synthesis of multi‐band filters based on multi‐prototype transformation

open access: yesIET Microwaves, Antennas & Propagation, 2021
In this article, a new synthesis method for generalized multi‐band filters has been proposed. Different from the traditional frequency transformation method, which transforms a low‐pass prototype into a multi‐band filter, multiple low‐pass prototypes ...

Efficient reconstruction of band-limited sequences from nonuniformly decimated versions by use of polyphase filter banks [PDF]

open access: yes, 1990
An efficient polyphase structure for the reconstruction of a band-limited sequence from a nonuniformly decimated version is developed. Theoretically, the reconstruction involves the implementation of a bank of multilevel filters, and it is shown that how

On the Designing of Spikes Band-Pass Filters for FPGA [PDF]

open access: yes, 2011
In this paper we present two implementations of spike-based bandpass filters, which are able to reject out-of-band frequency components in the spike domain. First one is based on the use of previously designed spike-based low-pass filters.

Current state and development prospects of design and technology of ceramic filters for on-board microwave equipment

open access: yesФизика волновых процессов и радиотехнические системы, 2019
The article considers the main design and technology issues of ceramic filters for on-board receiving and transmitting microwave equipment on the example of the development of the branch of RFNC-ARIEP RIMS named after Yu.E. Sedakov. Thetypes of band-pass

Single‐ and triple‐band bandpass filters using novel perturbed isosceles right‐angled triangular SIW cavities

open access: yesIET Microwaves, Antennas & Propagation, 2021
Herein, a rigorous derivation of an isosceles right‐angled triangular (IRT) metallic cavity is analysed. Then, the transverse field components in the IRT substrate‐integrated waveguide (SIW) cavity are derived, and the expression of the resonant ...

Practical formulation of the relation between filter specifications and the requirements for integrator circuits [PDF]

open access: yes, 1989
The design of integrated, high-frequency, continuous-time filters has made considerable progress in the past few years. As the signal frequencies increase the design of the integrator circuits used in most of these filters becomes more critical.

Design of a Compact Balanced Tri-band Bandpass Filter Using Simple Planar Resonator with Wide Stop-band and High Selectivity [PDF]

open access: yesAUT Journal of Modeling and Simulation, 2021
The most balanced multiband band-pass-filters have some remarkable properties while provide a trade-off between design goals. Additionally, few of them have provided a structure capable of satisfactory harmonic suppression.
