Notes:
1* Higher frequencies can be achieved either by using higher frequency crystals or by low noise analog harmonic
multiplication. Both methods have advantages and drawbacks. If lowest possible phase noise on the noise floor is most important
– high frequency crystal will be used. If phase noise close to the carrier and aging are more important – multiplication will be
used. Please consult factory for your specific requirement.
2* Aging rate is usually proportional to the operating frequency, unless higher frequency is achieved by multiplication.
Keep it in mind while specifying aging.
3* Phase noise deteriorates with frequencies going higher. If analog multiplication is used to achieve higher frequency
the phase noise roughly follows the formula of additional 20LogN, where N is a multiplication factor across entire frequency
offset range. If higher frequency is achieved by using higher frequency crystal phase noise close to the carrier deteriorates due to
the lower Q of the crystal and is usually worse, compared to multiplied solution. On the noise floor, however it remains more or
less the same. This design usually starts utilizing multiplication techniques in the range of 25 MHz to 35 MHz.
