Furthermore, electromagnetic interference (EMI) issues are reduced because only low orders of harmonics are applied to the gate of the main power amplifier. A system that incorporates such a wireless transmitter and methods of operating the same are also described herein.

Abstract: A method and system for generating a job alert. According to embodiments of the present invention, before a target job is processed, a characteristic of input and output of the target job in at least one stage is determined through analyzing a historical job, and a resource overhead associated with the processing of the target job is calculated based on the characteristic of input and output.
