Abstract :
Purely digital RF Transmitters of minimal footprint and power consumption and of acceptable performance for a wide range of applications are built out of Pulse Direct Digital frequency Synthesizers with spurs-suppression dithering and modulation capability. Several basic modulation schemes (FM/FSK/PM/PSK/AM/ASK) applied to Pulse Direct Digital frequency Synthesizers are considered.
