Abstract

Ovaj rad opisuje postupak projektiranja radiofrekvencijskog pojačala snage s praćenjem ovojnice, koje radi na 2.4GHz. Ispitane su karakteristike HCB tranzistora kao pojačala snage i sklopke razina napajanja. Ispitana je topologija za preklapanje 3 razine napajanja. Provedeno je mjerenje korisnosti pojačala, sa i bez sustava za praćenje ovojnice.

Abstract (english)

This thesis explains process of development of radio-frequency power amplifier with envelope tracking, operating at 2.4GHz. HCB transistor is characterised as power amplifier, as well as supply rail switching element. Topology for switching 3 voltage supply rails is tested. Power amplifier efficiency is measured, with and without envelope tracking.
