I am using HMC853 for one of the designs. The datasheet specifically calls for the base and Vee pins to be connected to -3V3 but I can't really see why.
Is it possible to use a non-inverted 3V3 rail instead? If yes, is the circuit on the right correct?

Would that also work for HMC720, HMC850, HMC853, HMC858?
