Measurement is at the package pin on the output of the Tx/Rx switch. It does not degrade more than 2 dB across
temperature and an additional 1 dB across all processes. Power adjustment will span nominally from –30 dBm to
+10 dBm in 21 steps @ 2 dBm / step.

Measured with output power set to nominal (0 dBm) and temperature @ 25°C. If trap filter is needed must meet reference
board size requirements.
