Title: Wayne D Tattershall: Innovator in RF Power Amplifier Technology
Introduction
Wayne D Tattershall is a notable inventor based in Cedar Rapids, IA (US). He has made significant contributions to the field of radio frequency (RF) power amplifier technology. With a total of 2 patents to his name, Tattershall's work has advanced the efficiency and functionality of RF systems.
Latest Patents
Tattershall's latest patents include innovative designs that enhance power amplifier circuitry. The first patent, titled "High efficiency path based power amplifier circuitry," discloses a system comprising a first transmit path, a second transmit path, and a third transmit path. The first transmit path features a first RF power amplifier and alpha switching circuitry, which is coupled to the output from the first RF PA. The second transmit path includes a second RF PA and beta switching circuitry, while the third transmit path incorporates a third RF PA.
The second patent, "Dual primary switched transformer for impedance and power scaling," addresses the reduction of power in series and parallel combined transformers while maintaining efficiency. This design includes a switch between a first primary inductor and a second primary inductor, allowing for at least two operational modes. In high power mode, the switch remains open, enabling normal operation of the series combined transformer. Conversely, in low power mode, the switch is closed, shutting down one amplifier from each of two differential amplifier pairs, thus allowing the transformer to operate efficiently at lower power levels.
