Abstract :
MMIC Local Oscillator for 16 QAM digital microwave systems has been developed. The Local oscillator is constructed with a low phase noise VCO and a new PLL for low phase noise performance. This low phase noise performance allows the developed MMIC local oscillator to be used in 16QAM systems.
