Notes:

Due to the high gain of the BGA430 RF blocking at the supply pin (VCC) has to be done

very carefully. Abroad 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 circuit may oscillate.
