Samsung patents circuit that fine-tunes power for satellite signals
Samsung describes an electronic device that uses a switch to measure the voltage supplied to a power amplifier and the voltage actually reaching the amplifier. By comparing these two measurements, the device adjusts the power supply to ensure the signal sent to a satellite base station is stable.
In the filing’s own words
An electronic device is provided. The electronic device includes a power amplifier (PA) amplifying a RF signal to be transmitted to a satellite base station, a first power amplifier power management integrated circuit (PA PMIC) supplying power to the PA, a first switch connecting one of an output port of the first PA PMIC and an input port of the PA to the first PA PMIC, and a communication processor, wherein the communication processor is configured to control the first switch to connect the output port of the first PA PMIC to the first PA PMIC and control the first PA PMIC to measure an output voltage of the first PA PMIC, control the first switch to connect the input port of the PA to the first PA PMIC and control the first PA PMIC to measure a supply voltage of the PA, determine the difference value between the output voltage of the first PA PMIC and the supply voltage of the PA, and adjust the output voltage of the first PA PMIC based on the determined difference value.
What exactly they claim (claim 1)
1. An electronic device, comprising: a power amplifier (PA) amplifying a RF signal to be transmitted to a satellite base station; a first power amplifier power management integrated circuit (PA PMIC) supplying power to the PA; a first switch connecting one of an output port of the first PA PMIC and an input port of the PA to the first PA PMIC; and a communication processor, wherein the communication processor is configured to: control the first switch to connect the output port of the first PA PMIC to the first PA PMIC and control the first PA PMIC to measure an output voltage of the first PA PMIC, control the first switch to connect the input port of the PA to the first PA PMIC and control the first PA PMIC to measure a supply voltage of the PA, determine a difference value between the output voltage of the first PA PMIC and the supply voltage of the PA, and adjust the output voltage of the first PA PMIC based on the determined difference value.
