Patent ID: 11870512
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. The closed-loop power control system of claim 1, wherein the system comprises a first signal path for a first polarization and a second signal path for a second polarization,
wherein the first signal path comprises the first power amplifier, the first output power detector, the first processor, the first DAC, the first controller, and the second processor, and
wherein the second signal path comprises:
a second power amplifier;
a second output power detector configured to detect a second output power level Pdet of the second power amplifier;
a third processor configured to determine a second analog gain Greq for a second controller and a second gain dGain for a second DAC based on a second accumulated error between the second output power level Pdet and the target EIRP; and
a fourth processor configured to set a second variable gain GCreq of a second VGA coupled to an input of the second power amplifier.
