Dans cet article, des préamplificateurs distribués hybrides de 2 à 10 GHz utilisant deux et trois amplificateurs distribués à un étage en cascade sont présentés. Ces amplificateurs produisent des gains de puissance disponible nettement supérieurs aux préamplificateurs distribués classiques utilisant le même nombre de dispositifs actifs. Les résultats de simulation montrent l'avantage du préamplificateur proposé par rapport au préamplificateur conventionnel. Les résultats mesurés des deux configurations réalisées de préamplificateurs utilisant deux et trois amplificateurs distribués à un étage en cascade sont présentés. Chaque configuration montre que le gain de puissance disponible peut être augmenté en augmentant l'impédance caractéristique entre les étages des amplificateurs distribués à un étage en cascade. Le gain de puissance disponible mesuré pour deux étages montre une amélioration de 18 dB à 20 dB, et pour trois étages, une amélioration de 26 dB à 31 dB sur la bande de fréquence 2-10 GHz, à mesure que l'impédance caractéristique inter-étages augmente de faible à un niveau élevé. Des pertes de retour d'entrée et de sortie supérieures à -10 dB et une isolation entrée-sortie supérieure à -55 dB au début de la bande et supérieure à -45 dB à la fin sont obtenues. Cette approche fournit également une bonne performance en matière de facteur de bruit mesuré d'une moyenne de 4 dB sur la bande de fréquences 2-10 GHz pour deux et trois étages en cascade. Le retard de groupe des deux amplificateurs en cascade est mesuré. Ses performances plates prouvent la viabilité de cette approche qui convient aux communications optiques numériques et aux applications impulsionnelles.

Abstract: In this paper 2-10 GHz hybrid-distributed preamplifiers using two and three cascaded single stage distributed amplifiers are demonstrated. These amplifiers produce available power gains significantly higher than conventional distributed preamplifiers using the same number of active devices. Simulation results show the advantage of the proposed preamplifier over the conventional one. Measured results of the two realised configurations of preamplifiers using two and three cascaded single stage distributed amplifiers are presented. Each configuration shows that the available power gain can be increased by increasing interstage characteristic impedance of the cascaded single stage distributed amplifiers. The measured available power gain for two stages shows an improvement from 18 dB to 20 dB, and for three stages an improvement from 26 dB to 31 dB across the 2-10 GHz frequency band, as the inter-stage characteristic impedance is increased from low to high level. Input and output return losses better than -10 dB, and input-output isolation better than -55 dB at the beginning of the band and better than -45 dB at the end are achieved. This approach also provides a good measured noise figure performance of an average of 4 dB across the 2-10 GHz frequency band for both two and three cascaded stages. The group delay of both cascaded amplifiers are measured. Its flat performance proves the viability of this approach which is suitable for digital optical communication and pulse applications.
