HMC943A Detector Pins

Question

What is the best way to terminate the VDET and VREF pins if the detector circuit is not being used? 
 Is it OK to connect these pins to ground? Or must they be left open, not-connected? 
 Thank you.

Hi GeoffatCPI, 
 A good amount of our customers leave these pins open and this has not posed a problem. This is the most common configuration if these pins are going to be unused. 
 Thanks,
