Using active bias controller for HMC1065


I need two 3V supplies for the HMC1065, one for VDD and one for VDLO. These have to be switched on at the same time, but cannot be commoned, as the gate bias setting is based on monitoring IDLO. Unfortunately, AD's active bias controllers have only one 3V output...

How have folk got around this problem? Do I use an op-amp buffer to source VDD at 90 mA? This seems inelegant.
