1. A remote radio head (RRH) comprising:
a plurality of RF power amplifier (PA) transmit paths, each of the plurality of RF amplifier transmit paths including at least one RF power amplifier; and
means for dividing a communication channel such that each RF power amplifier operates over a frequency bandwidth which allows efficient operation of the RF power amplifier and wherein each power amplifier (PA) transmit path is tuned for operation at a respective one of a plurality of different center frequencies (f0, f0+Δf, . . . f0+(n−1) Δf where n is an integer corresponding to the number of RF PA transmit paths and Δf is a frequency offset.
