Designing an asymmetric Doherty amplifier as a final stage RF power amplifier

, 2016
Tässä työssä toteutetaan korkeatehoinen asymmetrinen Doherty-vahvistin. Doherty-vahvistimen täytyy toimia 2110– 2170 MHz taajuusalueella ja kyetä vahvistamaan LTE (Long Term Evolution)-signaalia täyttäen 3GPP (Third Generation Partnership Project ...
