Title: The Innovations of Marc R. Sheade

Introduction

Marc R. Sheade is an accomplished inventor based in Cupertino, CA. He has made significant contributions to the field of technology, particularly in the area of frequency conversion and signal amplification. With a total of 2 patents to his name, Sheade continues to push the boundaries of innovation.

Latest Patents

One of his latest patents is the Plural Band Converter. This frequency converter utilizes a balanced bridge mixer of switching elements, such as field-effect transistors (FETs). A local oscillator supplies control signals to the gate terminals of the transistors. The device modulates a carrier at intermediate frequency (IF) or radio frequency (RF) for data communication. The output signals are processed through branches of an output circuit, each equipped with a bandpass filter tailored to specific output signals. Additionally, the design includes a switchable impedance circuit to maintain a constant impedance characteristic.

Another notable patent is the Detector Log Video Amplifier (DLVA). This device features a first RF detector that identifies power levels of received RF signals within a specific range. It produces corresponding video frequency signals that are logarithmically proportional to the detected signals. A second RF detector operates within a different power range, generating additional video frequency signals. The DLVA is designed to manage RF signals effectively, significantly reducing recovery time to less than 500 nanoseconds.

Career Highlights

Marc R. Sheade is currently employed at Raytheon Company, where he applies his expertise in developing advanced technologies. His work has been instrumental in enhancing communication systems and signal processing techniques.
