The gain & level diagram above assumes a 2
dB output backoff at the power amplifier as a
tradeoff between linear operations (to keep the
modulation sidelobes reasonably low) and
maximum output power.
Tx/Rx Switch
Switch time: 25 ns.
Harmonics rejection
An LC filter is placed after the power amplifier to
reject the second and third harmonics. The
