Zabdiel Brito-Brito,Ignacio Llamas-Garro,L. Pradell-Cara,Alonso Corona-Chavez +3 more
- 01 Oct 2008
TL;DR: In this paper, a switchable bandstop filter is presented to switch between two different central frequency states while precisely maintaining a fixed bandwidth, which is achieved by choosing adequate resonator sections which are switched by PIN diodes.
Air-filled square coaxial transmission line and its use in microwave filters
Ignacio Llamas-Garro,Michael J. Lancaster,Peter Hall +2 more
- 03 Jun 2005
TL;DR: In this article, a suspended coaxial transmission line with an air propagation medium is presented, where short-circuit stubs suspend the center conductor of the coaxial structure which is used in the design of two dual-mode narrowband microwave filters.
