Design 5-V supply to be capable of greater than 200 mA.
Design 3.3-V supply to be capable of greater than 800 mA.
Supply to channel I and Q sides must be well matched and isolated from one another. Recommend using ferrite beads in series to the pin. The I and Q supplies are for IF amplifier (at pin 38 and 23), for RF input (at pin 33 and 29), and for IF path circuitry (at pin 35 and 27).
Pins 7 and 16 are supplies for digital circuitry, and they can have extra isolation in this path (TI recommends using ferrite bead in series to the pin).
Pins 12, 19, and 46 are supplies for the internal synthesizer; designer must take care not to have noise sources that can couple to it nearby.
Typically use 0.1-µF capacitors near the pins. Add extra capacitance values at specific frequencies if known interfering frequencies in system. See Pin Configuration and Functions for more recommendations on component value recommendations.
