Abstract

S razvojem tehnologije, sve više se razvijaju RF miješala koja su postala neophodna za rad većine elektroničkih uređaja. Najbitnije karakteristike miješala su dobitak pretvorbe i ulazna presječna točka trećeg reda. Komercijalnog miješalo ADL5801 postiže dobitak pretvorbe oko 0 dB, a za ulazni presječnu točku trećeg reda postiže vrijednost preko 25 dBm. Miješalo izvedeno u HCBT tehnologiji postiže vrijednosti dobitka pretvorbe preko 0 dB, a vrijednost ulazne presječne točke trećeg reda je oko 17 dBm. Izvedbom miješala sa otvorenim kolektorom postižu se vrijednosti dobitka pretvorbe oko 8 dB i ulazne presječne točke trećeg reda oko 15 dBm. Tada se otpornik RE može povećati toliko da je dobitak pretvorbe malo iznad 0 dBm i u tom slučaju ulazna presječna točka trećeg reda raste do čak 28 dBm.

Abstract (english)

The development of technology resulted in a fastar development of RC mixers, which have become indispensable for most electronic appliances' operations. The most essential characteristics of a mixer consist in conversion gain and third-order intercept point. The commercial mixer ADL 5801 brings about 0 dB conversion gain, while it reaches the value over 25 dBm for the third-order imput intercept point. The mixer implemented in HCBT technology achieves the conversion gain value over 0 dB and the value of the third-order input intercept point comes to around 17 dBm. In the implemantation of an open- collector mixer, the values of conversion gain reach around 8 dB and the ones for the third-order input intercept point reach around 15 dBm. In that case, the RE resistor can be empowered so much that the conversion gain gets a bit above 0 dBm. Consequently, the third-order input intercept point raises even to 28 dBm.
