ADF4150HV RFIN single-ended or differential connection

Question asked by sss on Jul 21, 2017

Hi all,

 

In the datasheet page 23 @ ADF4150HV, it say following.

MICROWAVE PLL
For best performance and to achieve maximum power transfer,
it is recommended that a differential connection be used.

 

In generally, what is the difference specific PLL performance between single-ended and differential connection from vco to RFin +/- ?

 

What is the point (superiority / inferiority) when choosing single ended input or differential input configuration with priority on PLL characteristic performance without considering physical condition (device)?
harmonics? noise? Output level? Other?

 

Can you give us a general comment on a simple comparison of both PLL configuration ?

 

Best regards,
sss
