NOTE ON CORRECT USE
(1) Observe precautions for handling because of electrostatic sensitive devices.
(2) Form a ground pattern as wide as possible to keep the minimum ground impedance (to prevent undesired
oscillation).
(3) Keep the track length of the ground pins as short as possible.
(4) Connect a bypass capacitor (e.g. 1 000 pF) to the V
CC
pin.
(5) I, Q DC offset voltage should be same as the I, Q DC offset voltage (to prevent changing the local leak level with
power save control.)
