Abstract
Described are concepts, systems and techniques for dividing a communication channel such that no single radio frequency (RF) power amplifier (PA) in a remote radio head (RRH) operates over an excessively wide frequency bandwidth. This allows efficient operation of the RF PA wherein each 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.
