Abstract
U ovome je radu prikazan postupak projektiranja radio-frekvencijskog pojačala snage sa HCBT-om za rad na frekvencijama 900MHz i 2,4GHz. Definirani su parametri koji će se određivati tijekom projektiranja: pojačanje snage, kolektorska efikasnost, efikasnost dodane snage, točka kompresije, S parametri i stabilnost. Objašnjene su karakteristike mikrotrakastih linija. Opisana je struktura bipolarnog tranzistora s horizontalnim tokom struje. Prilagodba impedancije je izvedena pomoću L-mreže za frekvenciju 900MHz i pomoću stuba za frekvenciju 2,4GHz. Za oba pojačala je prikazana istosmjerna analiza i prema njoj određivanje vrijednosti impedancije trošila za maksimalan prijenos snage metodom load pull. Parametri pojačala su simulirani u programu Advanced Design Systems s modelima HCBT-a, mikrotrakastih linija i komponenata iz Muratinog kataloga. Tiskana pločica je projektirana u programu KiCad.
Abstract (english)
This thesis shows a radio-frequency power amplifier designing procedure with HCBT for frequencies 900MHz and 2.4GHz. Main power amplifier parameters were defined: power gain, collector efficiency, power added efficiency, compression point, S parameters, and stability. Microstrip line characteristics were described. Structure of Horizontal Current Bipolar Transistor was shown. Impedance matching was derived with L-network for a frequency of 900MHz, and with stub for a frequency of 2.4GHz. They have presented DC analyses for both amplifiers, and, with these results, have determined the value of impedance for which is maximum power transfer with the load-pull method. All parameters were simulated in Advanced Designs Systems software with models of HCBT, microstrip lines, and components from the Murata catalog. PCB was designed in KiCad software.
