HMC608 low-gain mode

Hi,

 

A couple of questions regarding using the HMC608 in low-gain mode (i.e. pin 23 left floating):

 

* Is the P1dB affected by using low-gain mode? If so, are you able to tell me what it is?

* I'm finding that I need a more negative Vgg voltage to achieve the 67mA current draw in low-gain mode than I need in high-gain mode to achieve the 310mA draw (typically <-4V in low gain mode compared to ~-2.9V in high-gain). Is this to be expected, or is there something wrong here?!

 

Many thanks,

Nial
