ADF4150 Noise characteristics test conditions

Hello

I have a question about ADF4150.


I would like to know about the RF output buffers: -75dBc Typ of Spurious Signals Due to PFD Frequency in the data sheet P4.

Question

Please tell me about the conditions when this data was acquired.

The information I want to know is the same as the content described in Note 2 on page 4 of the data sheet.

I would appreciate it if you could reply.

Best Regards,

Knj
