Function
Ground connection of the power
amplifier.
The RF ground return path of the
power amplifier output PAOUT (pin
9) has to be concentrated to this
pin.
RF output pin of the transmitter.
A DC path to the positive supply VS
has to be supplied by the antenna
matching network.
Disable pin for the complete
transmitter circuit.
A logic low (PDWN < 0.7 V) turns
off all transmitter functions.
A logic high (PDWN > 1.5 V) gives
access to all transmitter functions.
PDWN input will be pulled up by
40 µA internally by either setting
FSKDTA or ASKDTA to a logic
high-state.
