Patent ID: 11962338
Assignee: QORVO US, INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 5:
6. The transceiver circuit of claim 1, wherein the calibration circuit is further configured to:
determine a reference voltage and a reference input power;
determine a reference frequency among the plurality of calibrated frequencies within the modulation bandwidth;
determine a reference target voltage based on an expected root-mean-square (RMS) of a modulated voltage to be provided to the power amplifier circuit for amplifying a radio frequency (RF) signal; and
for each of the plurality of calibrated frequencies:
determine a respective gain of the power amplifier circuit that amplifies a test signal generated at the calibrated frequency and in the determined reference input power based on the determined reference voltage;
adjust the respective gain based on a determined compression gain to determine a compressed gain;
determine a respective modulated voltage and a respective input power that will cause the power amplifier circuit to have the compressed gain when amplifying the test signal at the calibrated frequency; and
store the respective modulated voltage and the respective input power in a temporary voltage LUT.
