Title: The Innovations of Andrew Gordon Summers
Introduction
Andrew Gordon Summers is a notable inventor based in Cambridge, GB. He holds a total of 4 patents that showcase his contributions to the field of electronics and communication systems. His work primarily focuses on enhancing the performance and reliability of transmitters.
Latest Patents
One of his latest patents is titled "Transmitter RF Power Control." This invention describes an electronic system designed to accurately control the RF output power from a power amplifier. The system utilizes a multiplier to multiply the output power by itself, generating a DC component that is fed to a variable gain amplifier. This amplifier provides a controlling signal via a comparator and an integrator to the power amplifier. The transfer function between the controlling signal and output power is notably linear, even during dynamic variations. This system is particularly beneficial for TDMA applications that require a large dynamic range of leveled output powers, allowing for a fixed filter function to shape the transmitted burst.
Another significant patent is "Transmitter Tolerant to Crystal Variations." This invention outlines a transmitter designed to transmit data from an end-point. It includes a reference oscillator, a low pass filter, a modulation filter for providing an over-sampled modulated signal, a synthesizer, and a sine wave generator. This configuration ensures reliable data transmission even in the presence of crystal variations.
