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) Running lower DC supply voltage will reduce extra heat from the unit 4) In many cases, unit may work with frequency under 200MHz and above 800MHz 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 Rev.B 4
