ADL5380 Adj Pin

Hi

 

What is the best way to make the ADL5380 ADJ voltage configurable to achieve the best possible IIP3 at different frequencies? . Is it a good idea to use a DAC to provide a variable Vadj value?

 

How can I maintain output Vpp If Vadj is high (>4.5V)? Is it possible to put an external common-mode voltages to the I/Q pos/neg outputs to maintain the output swing?


Thanks
