HIGH Q InP-BASED VARACTOR DIODES
We report on high quality-factor Heterostructure Barrier Varactor making benefit of epitaxial stacking and planar integration, with a cut-off frequency in the far infrared region. To this aim, high doping concentrations in the depletion (2x10 17 cm) and contact (1x10 cm) InGaAs regions lattice matched to an InP substrate and an InAlAs/AlAs blocking barrier scheme were used. Planar integration o...
متن کاملPlanar Varactor and Mixer Diodes Fabricated Using InP-Based Materials
This paper reports on a planar integrated technology which, unlike previous approaches, utilizes InP-based materials and airbridge technology to reduce parasitics by avoiding the use of a bridge-supporting dielectric. Verticalheterojunction varactors (VHV) and mixers were grown by the in-house Metalorganic-Chemical Vapor Deposition (MOCVD) system on S.1. InP substrates. A novel process is prese...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولthe role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
15 صفحه اولVARACTOR DIODES The Nuts and Bolts of Tuning Varactors
M any electronic systems must be tuned through the variation of reactance of one or more circuit elements. In these applications it is often desirable to perform this tuning under electronic rather than manual control. Tuning varactor diodes, which are pn junction devices that act as voltage controlled variable capacitors, can perform this function, and are used in a wide range of product appli...
