(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 VCC 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.)
