TRANSMITTER AND METHOD OF PROCESSING TRANSMISSION SIGNALS

摘要

A transmitter and method are provided for processing a transmission signal. The transmitter includes an FEM that switches a plurality of band signals for a first and second communication scheme, wherein the band signals for the first communication scheme include a first HB signal, a second HB signal, a first LB signal, and a second LB signal, and the band signals for the second communication scheme include a third LB and a third HB signal; a first PAM including a first power amplifier that amplifies the third HB signal, a second power amplifier that amplifies the first HB signal, and a third power amplifier that amplifies the first LB signal; and a second PAM including a fourth power amplifier that amplifies the third LB signal, a fifth power amplifier that amplifies the second HB signal, and a sixth power amplifier that amplifies the second LB signal.

1. A transmitter comprising:
a Front End Module (FEM) that switches a plurality of band signals for a first communication scheme and a plurality of band signals for a second communication scheme, wherein the plurality of band signals for the first communication scheme include a first high band signal, a second high band signal, a first low band signal, and a second low band signal, and the plurality of band signals for the second communication scheme include a third low band signal and a third high band signal; a first Power Amplifier Module (PAM) including a first power amplifier that amplifies the third high band signal, a second power amplifier that amplifies the first high band signal, and a third power amplifier that amplifies the first low band signal; and a second PAM including a fourth power amplifier that amplifies the third low band signal, a fifth power amplifier that amplifies the second high band signal, and a sixth power amplifier that amplifies the second low band signal.
