Not all combinations are available. Consult Factory.
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* 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.
