*The EVM specification is obtained with a signal generator that has an EVM level
<0.7%.
Note 1. The PA module must operate with gated bias voltage input at 1% to 99% duty cycle.
Note 2. No external matching components. Antenna port is a DC short to GND.
Note 3. Values to be agreed upon characterization data review: current, gain, return loss, detector sensitivity, and output power.
Note 4. The output power for channels 1 and 13 may be reduced to meet FCC restricted band requirements.
Note 5: EVM at lower output power values will never exceed nominal operating power EVM. EVM should be monotonic from 0dBm to rated out-
put power.
