US 2016/0241303 A1 · Upstream power amplifier

Abstract

A communication device includes a communication interface, a number of variable power amplifiers (VPAs), and a processor. Some of the VPAs are configured to process analog signals to generate processed analog signals (e.g., each VPA configured to process one of the analog signals to generate one of the processed analog signals based on a respective VPA control signal). A composite VPA processes a summation of the processed analog signals, which are generated by certain of the VPA, to generate a processed composite signal based on a composite VPA control signal. The processor generates the a first, a second, and a composite VPA control signals based, at least in part, on configuration information from another communication device via the communication interface. The processor may be configured to consider other information as well, such as locally generated information (within the communication device), operational history, current operating conditions, etc.
