The goal of this project is to design and simulate these submodules from an educational perspective. The modulator is implemented as a single-ended common-base Colpitts oscillator with modulation capabilities added by means of varactor diodes. The carrier frequency of the presented modulator is tunable from 88 MHz to 108 MHz and the achieved modulation linearity for a sawtooth baseband signal is approximately 34 dB over the tuning range. The presented mixer consist of a double-balanced Gilbert-type topology with 29.5 dB (tunable) gain, 23 mW power consumption, high Input-Output isolation and single-ended output achieved by means of an active load. The project was carried out in the scope of the bachelor graduation project in the bachelor of electrical engineering at the Delft University of Technology.
