A FAST TUNING HF DDS SYNTHESIZER
The aim was to produce a DDS controller with minimum hardware, that would offer a good linear tuning rate at 10Hz steps.The project uses an AD 9850BRS from analog devices, an industry standard two line LCD display, two PIC16F84 processors to manage the DDS and display, an optical shaft encoder and a pair of MMIC amplifiers to generate up to +10dBm to drive a diode ring mixer.
