Comparison of on-wafer calibrations using the concept of reference impedance
Purroy Martín, Francesc; Pradell i Cara, Lluís (. MICROWAVE EXHIBITORS AND PUBLISHERS, 1993)
Text en actes de congrés
Accés obertA novel method that allows to compare different calibration techniques has been developed. It is based on determining the reference impedance of a given Network Analyzer calibration from the reflection coefficient measurement ... -
Control automático de nivel (ALC) de un SSPA en banda Ka
Corbella Sanahuja, Ignasi; Purroy Martín, Francesc (1991)
Text en actes de congrés
Accés obertThis communication describes the design of an Automatic Level Control (ALC) for the transmiter of a CODE (Co-operative Olympus Data Experiment) earth station. The goal of the ALC system is to keep constant the transmited ... -
Development of self-calibration techniques for on-wafer and fixtured measurements: a novel approach
Pradell i Cara, Lluís; Purroy Martín, Francesc; Cáceres, M. (. MICROWAVE EXHIBITIONS AND PUBLISHERS, 1992)
Text en actes de congrés
Accés obertNetwork Analyzer self-calibration techniques - TRL, LMR, TAR- are developed, implemented and compared in several transmission media. A novel LMR (Line-Match-Reflect) technique based on known LINE and REFLECT Standards, is ... -
New Theoretical Analysis of the LRRM Calibration Technique for Vector Network Analyzers
Purroy Martín, Francesc; Pradell i Cara, Lluís (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2001-10-31)
Article
Accés obertIn this paper, a new theoretical analysis of the four-standards line-reflect-reflect-match (LRRM) vector network-analyzer (VNA) calibration technique is presented. As a result, it is shown that the reference-impedance (to ...
