Abstract
Predmet završnog rada je RF niskošumno pojačalo (LNA) kao ulazni stupanj radio-prijemnika. U teorijskom sažetku se razmatra šum općenito, utjecaj elektroničkih sklopova na njegovu razinu u signalu i važnost niskog faktora šuma niskošumnog pojačala. Razmotreno je kako se prilagođavaju ulazne i izlazne impedancija u RF sklopovlju i kako se njegov utjecaj na signal opisuje S-parametrima. Definirane su mjere linearnosti pojačala i dan pregled osnovnih spojeva tranzistora. U drugom dijelu rada ranije objašnjena teorija se primjenjuje na primjeru projektiranja niskošumnog GSM pojačala korištenjem bipolarnog tranzistora s horizontalnim tokom struje pomoću softverskog paketa ADS. U zaključku se projektirano pojačalo uspoređuje s jednim komercijalno dostupnim pojačalom.
Abstract (english)
The subject of this thesis is the role of the low-noise amplifier (LNA) as the first amplification stage in a radio recevier. In the theoretic summary we examine noise in general and how electronic devices affect the signal-to-noise ratio. An argument is made why it is important that the low noise amplifier indeed has a low noise figure. Next, we take a look at impedance matching in RF circuits and how we use S-parameters to characterize the effect of 2-port networks on signal propagation. We define how to measure linearity in amplifiers and take a look at the basic transistor configurations. In the second part of the thesis the aforementioned theory is put into practice by designing a GSM LNA using the horizontal current bipolar transistor (HCBT) and the ADS software package. In the conclusion we examine if the designed amplifier is any good by comparing it with a commercially available one.
