Abstract
U ovom radu tehnika digitalnog predizobličenja signala primijenjena je na RF pojačalo snage klase AB izvedeno u HCBT tehnologiji. Tehnika je izvedena korištenjem memorijskih polinoma. Za potrebe rada napravljen je Salehov model pojačala. Model je korišten za razvoj i testiranje tehnike digitalnog predizobličenja u Matlab-u kao i za generiranje predizobličenog signala kojim je karakterizirano stvarno pojačalo. Napravljeno je mjerno okruženje za testiranje linearnosti pojačala. Analiziran je utjecaj reda polinoma i dubine memorije na spektralni odziv pojačala na širokopojasni 16-QAM signal. Uz širinu pojasa 1 MHz i 5. red polinoma postignuto je smanjenje spektralnog širenja od približno 10 dB. Povećanjem širine pojasa signala, efikasnost tehnike se smanjuje zbog izraženijih memorijskih efekata koji maskiraju djelotvornost linearizacije.
Abstract (english)
Technique of digitally predistorted signal was applied to AB class RF power amplifier implemented in HCBT technology. Technique was derived by using memory polynomial. For the purposes of this work Saleh amplifier model was made. Model was used for design and testing of digital predistortion technique in MATLAB as well as for generating digitally predistorted signal which was used for characterization of real amplifier. Measurement system for testing amplifier linearity was setup. Impact of the polynomial order and depth of memory on the amplifier spectral response on wideband 16-QAM signal were analyzed. Decrease of spectral regrowth of 10 dB was acomplished using the fifth order polynomial and 1 MHz signal bandwidth. By increasing the signal bandwidth, efficiency of the technique decreases because more pronounced memory effects.
