POWER SUPPLY AND CONTROL INPUTS

Because the ADRF5301 incorporates a negative voltage generator
(NVG) to operate with a single positive supply of 3.3 V applied to
the VDD pin, only one power supply is needed to power up the
ADRF5301-EVALZ. The control input is connected to the CTRL test
point, and the ground reference is connected to the GND test point.
On the supply trace, a 100 pF bypass capacitor filters the high-fre-
quency noise. Additionally, unpopulated component positions are
available for applying extra bypass capacitors.
On the control trace, there are provisions for an RC filter to elimi-
nate DC-coupled noise, if required by the application.
