Abstract
We present synthesis of low noise microwave signals from 9.5-10.5 GHz via optical frequency division and direct digital synthesis. Over the entire synthesized band we measure an absolute phase noise level of less than -100 dBc/Hz at a 1 Hz offset, corresponding to an oscillator instability of 2 × 10-15 at a 1 s averaging time.
