Abstract :
A 19GHz frequency-modulated continuous-wave TX based on a bandpass ΔΣ DDFS-driven RF frequency synthesizer is presented. Implemented in a 0.25μm SiGe process, the synthesizer draws 63mA from a 2.5V supply while achieving a 512MHz FM deviation with a 200Hz FM rate at a center frequency of 19GHz. The measured phase noise of the frequency synthesizer is -113.68dBc/Hz at 1MHz offset frequency from a 19GHz carrier
