Abstract
In this paper, a new RF/Microwave source is presented. This source is able to generate a Continuous Waveform (CW) signal as well as a modulated signal like GFSK for Bluetooth and GMSK for GSM. The RF source presented here is based on a direct modulation All-Digital Phase-Locked-Loop (ADPLL) architecture that was originally designed for a Bluetooth transmitter in the 2.4GHz in industry, science, and medicine (ISM) band. By doing some mod$cations, we were able to extend the frequency range of the source. The ADPLL requires a controlled signal from a Digital Signal Processor (DSP). The TMS32OC5402 DSP was chosen for this experiment.
