5.2.7. Downlink Final Amplifier
For the Node M/C x37 an MCPA (multi carrier power amplifier) is used.
This is an error-correcting feed-forward amplifier. It has a high output power while
maintaining superior intermodulation and linearity performance.

For the Node M/C x43 an MCPA (multi carrier power amplifier) with more output
power is used. This is an error-correcting feed-forward amplifier. It has a high output
power while maintaining superior intermodulation and linearity performance.
