Title: Richard M Schierbeck, II: Innovator in Power Amplifier Technology
Introduction
Richard M Schierbeck, II is a notable inventor based in San Diego, CA. He has made significant contributions to the field of power amplifier technology, holding 2 patents that showcase his innovative approach to enhancing radio communications.
Latest Patents
One of his latest patents involves multi-mode power amplifiers. These amplifiers are designed to support multiple radio technologies and frequency bands. In this exemplary design, a first linear power amplifier is utilized to amplify a first RF input signal for low band applications, providing a corresponding RF output signal. Additionally, a second linear power amplifier is employed to amplify a second RF input signal for high band applications. Each amplifier includes multiple chains that can be selected to amplify an RF input signal across various output power levels. The RF input signals can be phase modulated or quadrature modulated and may undergo pre-distortion to address the non-linearity of the power amplifier.
Another significant patent focuses on systems and methods for measuring the non-linear characteristics of a power amplifier. This method involves calculating a calibration waveform during a testing procedure. The amplitude and phase characteristics of this waveform are measured at the output of the power amplifier. Pre-distortion techniques are then configured based on these characteristics for use during normal operation periods of a transmitter.
