Distributed Amplifiers with Composite Left/right-handed Transmission Lines
The use of so-called “composite left/right-handed transmission lines” in the design of distributed amplifiers is discussed using a simple model for the active device. The simplified analysis performed herein shows that it is possible to modify the frequency response of forward and reverse power gains, a significant development which could lead to innovative distributed amplifier designs. © 2006...
متن کاملA compact very wideband amplifying filter based on RTD loaded composite right/left-handed transmission lines
The composite right/left-handed (CRLH) transmission line (TL) is presented as a general TL possessing both left-handed (LH) and right-handed (RH) natures. RH materials have both positive permittivity and positive permeability, and LH materials have both negative permittivity and negative permeability. This paper aims to design and analyze nonlinear CRLH-TL transmission line loaded with resonant...
متن کاملTunable Via-free Microstrip Composite Right/Left-Handed Transmission Lines Using MEMS Technology
In this contribution a tunable via-free microstrip composite right/lefthanded transmission line (CRLH-TL) is designed and simulated. To add tunability RF MEMS elements are implemented in the interdigital capacitors and stub inductors, which match the line impedance during tuning. The via-free design enables easy and low-cost fabrication. Additionally, tunable zero-order resonators (ZORs) using ...
متن کاملDevelopment of solitons in composite right- and left-handed transmission lines periodically loaded with Schottky varactors
The characteristics of composite rightand left-handed CRLH transmission lines periodically loaded with Schottky varactors are discussed in relation to the development of solitons. CRLH lines are highly dispersive and thus, when appropriately designed, compensate the effect of nonlinearity introduced by the Schottky varactors to support solitons. The reductive perturbation method applied to the ...
متن کاملLeaky wave antenna with amplitude controlled beam steering based on composite right/left-handed transmission lines
An antenna comprising two different composite right/left-handed transmission line structures is proposed which enables easy beam steering at an operation frequency of 10 GHz. The composite right/left-handed transmission lines are based on planar, periodically arranged via free unit cells, implemented in microstrip technology. Both transmission lines exhibit the infinite wavelength phenomenon wh...
