To read about the communications systems that the Lunar Module employed, here are two good links from the NASA Archives: https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19720023255.pdf and https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20090015392.pdf

The S-band transceiver was the primary transceiver used for TV, telemetry, biomedical data, and voice communications from the Lunar surface. It had an output power of  750 mW (QRPp!).  That signal then went to the S-band power amplifier, which boosted the signal to an outstanding "QRO" signal of 18.6 Watts.
