HMC705LP4E: cascading 3 chips and SSB phase noise

Hello,

 

1) What is the total SSB phase noise when cascading 3 HMC705LP4E ?

The input is a very clean 3GHz sin wave.

For each chip, the division ratio will be between 1 and 8 (from total bypass to divide by 512).

 

2) If I understand correctly the "FAQ: HMC Microwave Frequency Dividers by Analog Devices", if the last chip is configured as a divide-by-2, the output's duty cycle will be 50% no matter the division ratio on the other chips ?

 

Thank you
