Hi,

 

We have bought a HMC659 evaluation board and according to the datasheet, a +8 V DC should be applied to Vdd. However, on the evaluation board there is no Vdd, but a Vgg1 and Vgg2 and there is no clear information on how should the DC power supplies be applied.  Could you please guide us how to solve this problem?
