Method and apparatus for amplifying feedforward linear power using pilot tone hopping |
摘要 |
A method and apparatus for amplifying a feedforward linear power using a pilot tone hopping are disclosed. The method in a feedforward linear power amplifier system first determines an operating frequency signal for amplification from a radio frequency (RF) signal applied to the linear amplifier system. A pilot frequency signal is determined from the previously determined operating frequency signal, and the decided pilot frequency signal is hopped into an upper sideband or lower sideband of the operational frequency bandwidth of the applied RF signal and the determined pilot frequency signal is output to an input port of a main amplifier. One typical advantage of the method is that distortion component suppression characteristics in the wide operating frequency bandwidth are obtained by only one pilot signal generator and use of a control/detect device leads to simplicity of the circuit.
