Query about ADF4350's primary output power-down

Hi, there

 

Currently, I want to power down primary output of ADF4350 - RFoutA ports; while just let secondary outputs have LO - RFoutB. I went through datasheet, DB5 of R4 seems to help. As described in the datasheet, "DB5 enables or disables primary RF output, depending on the chosen value.

"

1, could DB5 of R4 help me?

2, if not, could you please help with other solution or give some comments on it?

 

thanks so much for your great help!

 

Br,

Wayne
