Notes:
Due to the high gain of the BGA430 RF blocking at the supply pin (VCC) has to be done
very carefully. A broad-band low impedance RF path to GND has to be provided at VCC.
If no appropriate RF blocking is used, RF can couple via the internal power lines to the
input and the device might oscillate.
