1. A method of transmitting a signal, comprising:
- receiving an input signal;
subdividing the input signal into a plurality of sub-bands, each sub-band containing a different spectral component of the input signal;
up-converting and amplifying each sub-band; and
combining the amplified sub-bands for transmission.

Abstract
An RF power amplifier architecture minimizes spurious emissions by breaking the transmitted signal into narrow spectrum sub-bands, amplifying each separately, and then combining the signals for transmission purposes.

11. A system comprising:
-
an antenna; a processing module to parse a received input signal into a plurality of sub-bands, each sub-band containing a different spectral component of the input signal; an amplifier to amplify at least one sub-band; and a combiner to combine the plurality of sub-bands for transmission by the antenna. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
