We are using the HMC924 in our design. As per the guidelines, Idd2 + 3 + 4 should be set to 170mA by tuning Vgg.
In our case we tried setting Vgg to 0, -1, -2V and in all three cases the current being drawn is a lot. We set a bench top supply to provide 5V and 300mA (current limit) and the current being drawn is more than 300mA and so that voltage drops to about 0.35V.
We have double checked our circuit (it is also attached to this post) and the soldering also seems fine.
Please advise on how to debug the problem.
