申请号：US14484377
申请日：2014-09-12
Applicant: RF Micro Devices, Inc.
Inventor： Miaofu Ding , Robert J. Baeten
CPC classification number: H03G3/30 , H03F1/302 , H03F3/195 , H03F3/245 , H03F2200/447 , H03G3/3042
Abstract: A power amplifier (PA) system with PA gain correction is disclosed. The PA system includes a PA having a bias voltage input; and electrothermal feedback circuitry coupled to the bias voltage input. The electrothermal feedback circuitry is configured to receive thermal feedback generated by the PA and maintain a substantially constant PA gain by automatically changing a bias voltage level at the bias voltage input based upon the thermal feedback.
