Title: Innovations of Richard E. Sherman
Introduction
Richard E. Sherman is a notable inventor based in Mesa, AZ (US). He has made significant contributions to the field of radio frequency (RF) technology, holding 2 patents that showcase his innovative approach to amplifier circuits.
Latest Patents
One of his latest patents is a "Power amplifier with VSWR detection and correction feature." This invention is designed to detect and measure output load mismatches in RF power amplifiers, adjusting their operating characteristics to minimize output signal distortion. The circuit utilizes a directional RF signal coupler to obtain a coupled reflected RF signal, which indicates the output load mismatch. By processing this signal, the circuit generates bias control signals to maintain the RF power amplifier within a linear operating range, thereby enhancing performance.
Another significant patent is the "Amplifier circuit and method for increasing linearity of the amplifier." This invention features an amplifier circuit that includes a limiter generating a phase modulated signal based on the RF input signal. It also incorporates an envelope detector that produces an envelope signal from the amplitude modulated component of the RF input. A delay compensation circuit processes this envelope signal to create a lead phase envelope signal, which is then used to generate a bias signal for the RF amplifier, improving its linearity.
