Power amplifier
The power amplifier is a three stage discrete amplifier. It amplifies the 0
dBm ( 2 dBm in PCN) TX signal to the desired output level. It has been
specified for 5.5...8.5 volts operation. There are 5 x 330
m
F capacitors in
the near vicinity of the power amplifier to alleviate supply voltage
degradation during TX burst.
