down by 6dB in 2dB steps.
4.5.6 Tune-Up
Procedures
Each RF power amplifier will be tested and tuned-up according to the test instruction. A part of the
test procedure is to trim and verify the correct output level at mid channel at the highest output
level, then verify the correct levels over the frequency band, by testing output power at lowest and
highest channel. The final test is to verify that the output power is correct at the different back off
levels.

The power amplifier is designed with an output power control loop to ensure the correct output
power over the frequency range, temperature changes and input voltage changes.
