In additional to work with R Bay, Inc. Prescaler, VCO, Power Divider and Amplifier, it also works with widely commercial available similar product. Keep in mind following will help you to improve the system performance: 1) With smaller Prescaler divide ratio, the better phase noise performance 2) erence phase noise play critical role for entire system performance 3) In most cases, unit will work with level under -3dBm with slightly phase noise degradation 4) In most cases, unit will work with frequency under 5MHz and above 25MHz 5) When sweep reference frequency, the switching time is around 300 µs 6) Different loop filter bandwidth can be specially ordered 7) Connection shown in application examples are short SMA coaxial cables 4
