Title: Innovations of Richard J Wiegand
Introduction
Richard J Wiegand is a notable inventor based in Severna Park, MD (US). He holds a total of 9 patents, showcasing his significant contributions to the field of radio frequency technology. His work has advanced the capabilities of digital RF memory systems, making a lasting impact on the industry.
Latest Patents
Wiegand's latest patents include a Spur Reduction System for Digital RF Memory and a Modulated Single Channel Digital Radio Frequency Memory (DRFM). The Spur Reduction System employs a coherent radio frequency memory (CRFM) that utilizes a digital RF memory (DRFM) and a power limiter to maintain a consistent power level across a wide range of RF inputs. Additionally, it incorporates an RF noise generating mechanism to decorrelate spurious outputs. The Modulated Single Channel DRFM system is designed to store incoming RF signals in a digital memory and replicate them at the output. This system mixes the input RF signal with a modulated local oscillator signal to produce an intermediate frequency (IF) signal, which is then digitized and stored. The stored values can be retrieved after a programmed delay, allowing for the output RF signal to closely replicate the input.
