We demonstrate a technique to obtain wide synthesized tunability from the local oscillator (LO) of a low-noise, fixed-frequency microwave reference whose noise is suppressed by a high-Q cavity discriminator operated in a passive mode. The results show that

Following our earlier work on a new approach to synthesising the Cs hyperfine frequency of 9.192 GHz, we describe developments on its further refinements. The salient feature of our design is that it is based mainly on frequency division and requires no
