2010 Photonics Global Conference, 2010
Photonic signal processing offers the prospect of realising extremely high multi-GHz sampling frequencies, overcoming inherent electronic limitations. This stems from the intrinsic excellent delay properties of optical delay lines. These processors provide new capabilities for realising high time-bandwidth operation and high-resolution performance.

Cooking Microwave Filters: Is Synthesis Still Helpful in Microwave Filter Design?
IEEE Microwave Magazine, 2020In "Recipe for Cooking Microwave Filters," we show the classic recipe for "cooking" with narrow-or moderate-bandwidth microwave filters.While the result of this recipe is generally effective [1] (the "cake" is only rarely not edible), the tendency of some "cooks" (often young microwave engineers) is to jump to the last two steps as quickly as possible.

IEEE Transactions on Microwave Theory and Techniques, 1958
In order to obtain filters capable of handling very high power, the use of radial lines and uniform line discontinuities was investigated as the most promising approach. In this connection, it was necessary to consider equivalent circuit and interaction effects for H-mode radial line mated at each end to uniform TE 10 waveguide for taper angles of 45 ...

Modeling of Planar Microwave Filters
33rd European Microwave Conference, 2003, 2003An approach for modeling of planar microwave filters by the Method of Lines (MoL) is presented. The algorithm combines 2-D discretization of the cross-section with the numerically stable impedance/admittance transformation. To improve accuracy and efficiency of this approach, edge conditions are examined and the best edge position relative to the ...

Microwave superconducting filters
IEEE Transactions on Magnetics, 1991Four-pole, parallel-coupled microstrip line filters were fabricated using epitaxial YBa/sub 2/Cu/sub 3/O/sub 7/ (YBCO) films deposited by off-axis sputtering on LaAlO/sub 3/ substrates. Filters were made with and without superconducting ground planes.

Filters are two-port devices designed in such a way so that a group of specified frequencies is allowed to pass with little attenuation, while unwanted frequencies are rejected. They can also be designed to symmetrically or asymmetrically modify the amplitude and/or phase of a signal.

Microwave Communication Filters
1971 2nd European Microwave Conference, 1971This paper considers the various design procedures for microwave bandpass channel filters which are of sufficiently narrow fractional bandwidth such that they may be designed directly from low-pass prototypes. Initially, the more conventional forms are considered e.g., (Thompson, Butterworth, Chebychev, Elliptic Function etc.) and typical physical ...

Varactor Tuned Microwave Filters
MTT-S International Microwave Symposium Digest, 2005The design and realization techniques of varactor tuned microwave filters are presented. Novel filter circuits are used and these are realized using Suspended Substrate Stipline. Experimental devices exhibit broad tuning bandwidths and low dissipation loss. Both bandpass and band-stop filters are described.
