LO buffer reported so far always have very high power dissipation. I don't know in case of your design, but I also have to design LO buffer for passive mixer and for you can refer to commercial product specs or publications. @ pHEMT 0.5um process, 5V VCC, it always requires a current about 45 mA (see HMC485MS8G datasheet) or @3V VCC, it is 10 mA (see ADL5350 datasheet); @BiCMOS 0.25um process, the current is 9mA to 65 mA when VCC from 1.5 to 5 V (see A SILICON MMIC ACTIVE BALUN/RUFFER AMPLIFIER WITH HIGH LINEARITY AND LOW RESIDUAL PHASE NOISE)
