ENGLISH ABSTRACT: The thesis details the design, construction and experimental evaluation of 30W, 35W and 250W L-Band LDMOS Radar amplifiers. Each amplifier module contains an integrated high speed power supply in order to optimize RF pulse repeatability and to improve radar MTI factor (Moving Target Indication.) As part of the work, a pulsed RF measurement system for measuring the dynamic I-V curves of a power FET was developed. Work was also done on low impedance S-parameter measurement test fixtures for the characterisation of power FETs. These measurement systems generated design information which was used in the development of the L-Band power amplifiers AFRIKAANSE OPSOMMING: Hierdie tesis beskryf die ontwerp, bou en experimentele evaluering van „n 30W, 35W en 250W L-band LDMOS radarversterker. Elke versterker bevat ook „n geintegreerde hoë-spoed kragbron om optimum RF pulsherhaalbaarheid te verseker en die radar se „MTI (Moving Target Indication)‟ te verbeter. „n RF-pulsmetingstelsel is ook ontwikkel om die dinamiese I-V kurwes van „n hoë-krag FET te meet. Verder is daar ook gewerk aan „n toetsopstelling vir lae-impedansie S-parameters om hoë-krag FETs te karakteriseer. Hierdie toetsopstelling is gebruik om ontwerpsdata te genereer wat gebruik is in die ontwerp van die L-band kragversterkers. 2010-02-22T09:59:14Z 2010-08-13T14:58:57Z 2010-02-22T09:59:14Z 2010-08-13T14:58:57Z 2010-03 Thesis http://hdl.handle.net/10019.1/4092 en University of Stellenbosch 109 p. : ill. application/pdf Stellenbosch : University of Stellenbosch |
