Title: Innovations by Pravinkumar Premakanthan
Introduction
Pravinkumar Premakanthan is an accomplished inventor based in Delray Beach, FL (US). He has made significant contributions to the field of radio frequency (RF) technology, holding a total of 3 patents. His work focuses on enhancing the performance and efficiency of power amplifiers in RF transmitters.
Latest Patents
One of his latest patents is titled "Dynamic gain and phase compensation for power amplifier load switching." This invention provides methods and apparatus for gain and phase compensation in an RF transmitter. The RF transmitter includes at least one power amplifier (PA) that generates a transmitted signal. An RF power detector is coupled to the PA to detect the signal power of the transmitted signal. Additionally, an analog to digital (A/D) converter is connected to the RF power detector. A hysteresis unit generates a pulse in response to a power threshold being crossed, while a load switch control unit provides gain and phase compensation based on this pulse.
Another notable patent is the "Adaptive transmit power control system." This adaptive closed-loop transmit power control system does not require extensive factory calibration of power control loop bandwidths and feedback detect path gain settings. It automatically compensates for gain or slope variations in the analog feedforward and feedback paths to maintain system stability and meet performance specifications. The system utilizes an adaptive digital signal processing (DSP) architecture within the feedback path, eliminating the need for extensive factory calibration.
