Title: The Innovations of James C Braatz

Introduction

James C Braatz is a notable inventor based in Kent, WA (US). He has made significant contributions to the field of technology, particularly in the area of data transfer and signal processing. With a total of 3 patents to his name, Braatz has demonstrated his expertise and innovative spirit throughout his career.

Latest Patents

One of Braatz's latest patents is the Fibre Channel Transceiver. This invention provides Fiber Channel data transfer speeds and can be implemented in a lower performance process technology as a single unit, thereby reducing costs. The transceiver includes a serializer and deserializer, each having multiple lower frequency clocks to achieve the equivalent of a high-speed clock suitable for Fiber Channel systems. It effectively converts lower speed parallel data to higher speed serial data and vice versa, while also incorporating a digital frequency counter and phase detection circuit for synchronization. Additionally, comma detection is included for data word alignment.

Another significant patent is the Harmonic Rejection Gated-Switching Mixer. This invention addresses the rejection of local oscillator harmonic response in a mixing circuit. It features a pair of harmonic gating switches that are serially connected to the outputs of a balanced differential switching mixer. These switches are controlled by a gate clock signal that has twice the frequency of the local oscillator signal. The design allows for the suppression of specific harmonics, particularly the third and/or fifth harmonic, resulting in a simple and efficient circuit that can be integrated directly into a phase-alternating mixer structure for chopper-direct-conversion radios.
