Title: Brian Lindemann: Innovator in RF Amplifier Technology
Introduction
Brian Lindemann is a notable inventor based in Quincy, Illinois, who has made significant contributions to the field of radio frequency (RF) amplification. With a total of two patents to his name, Lindemann's work focuses on enhancing the efficiency and performance of RF amplifiers through innovative designs and techniques.
Latest Patents
Lindemann's latest patents include a Class D amplifier using Fs/4 modulation and envelope tracking power supplies. This high-power Class D amplifier/modulator is designed for use in RF ranges and is capable of implementing digital modulation schemes with high efficiency. The new amplifier design incorporates an envelope tracker unit that utilizes digital pulse-width modulation (PWM) to generate analog I and Q phase high voltage signal components and sign bits. These components are then processed through an Fs/4 modulator stage to produce a high-power RF signal that is modulated by the analog input signal. Another significant patent is focused on compensating for a radio frequency amplifier. This invention involves digitizing an analog RF input and feedback from the amplifier's output, calculating pre-distortion coefficients, and filtering the input using these coefficients before up-converting it to a carrier frequency for the RF amplifier.
