Journal ArticleDOI
Miniaturized Transmission Lines Based on Hybrid Lattice-Ladder Topology
TL;DR: In this article, a hybrid structure with unit cells that are a combination of lattice and ladder topologies is introduced, which dramatically increases the quality factor, miniaturization, and maximum frequency of synthetic transmission lines.
Journal ArticleDOI
Tunable Filters With Nonuniform Microstrip Coupled Lines
TL;DR: In this paper, a combline topology based wideband tunable filter design based on the combline structure is presented, where the structure of the filter must be modified by introducing additional degrees of freedom to the geometry of the coupled line segment.
Proceedings ArticleDOI
Switchable Bandpass Filter for 0.3-0.6 GHz
TL;DR: In this paper, a two-pole prototype has been fabricated using 10 discrete PIN diodes and is capable of covering the frequency range of 290 to 600 MHz in four steps (2-bit tuning).

Compact switchable filter for software-defined radio
TL;DR: A switchable bandpass filter as discussed by the authors includes a coupled line segment (comb) including a plurality of coupled transmission lines of substantially equal lengths that are each connected or otherwise coupled to the common RF ground at their first end, adjustable capacitors each coupled proximate a second end of respective ones of the transmission lines, and shunt switches coupled to points along a length of each transmission line.
Proceedings ArticleDOI
Multi-scale tunable filter covering a frequency range of 6.5:1
TL;DR: In this article, a multi-scale filter topology is proposed in the form of a switched comb-line structure loaded by varactors, which is capable of implementing a tunable frequency response with consistent performance over very large tuning ranges.
