DISTRIBUTED CLOSED-LOOP POWER CONTROL WITH VGA GAIN UPDATE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17731251 titled 'DISTRIBUTED CLOSED-LOOP POWER CONTROL WITH VGA GAIN UPDATE

Simplified Explanation

- The patent application describes a closed-loop power control (CLPC) system that has two signal paths for different polarizations. - The first signal path includes a power amplifier, an output power detector, and a processor to determine analog and digital gains based on the difference between the output power level and a target power level. - The second signal path includes a processor to set the gain of a variable gain amplifier. - The CLPC system can control the gain of the first signal path separately or as one signal path.


Original Abstract Submitted

A closed-loop power control (CLPC) system is disclosed that includes a first signal path for a first polarization and a second signal path for a second polarization. The first signal path includes a first power amplifier, a first output power detector configured to detect a first output power level of the first power amplifier, and a first processor configured to determine a first analog gain for a first controller and a first gain for a first digital-to-analog converter based on a first accumulated error between the first output power level and a target Effective Isotropically Radiated Power. A second processor is configured to set a first variable gain of a first variable gain amplifier coupled to an input of the first power amplifier. The CLPC can be configured to control the gain of the first signal path separately or as one signal path.
