Title: Innovations of James S. Lamb
Introduction
James S. Lamb is a notable inventor based in Portland, OR (US). He has made significant contributions to the field of test and measurement instruments, holding a total of 8 patents. His work is characterized by innovative designs that enhance the functionality and efficiency of measurement technologies.
Latest Patents
Among his latest patents is a test and measurement instrument that includes an asynchronous time-interleaved digitizer using harmonic mixing. This invention features a splitter that divides an input signal into multiple split signals, each retaining the full bandwidth of the original signal. The design incorporates harmonic mixers that mix these split signals with harmonic signals to produce mixed signals, which are then digitized by dedicated digitizers. Notably, the first-order harmonic of at least one harmonic signal differs from the effective sample rate of the digitizers, showcasing a sophisticated approach to signal processing.
Another significant patent is the wideband balun structure. This balun features positive and negative signal paths connected to a ninety-degree hybrid. The positive signal path includes a circuit trace and a phase shaper that provides a complete phase shift at Port 1 of the hybrid. Meanwhile, the negative signal path is equipped with a second-order phase shaper that compensates for signal loss and ensures a frequency band from DC to at least 15 GHz, with a transient response exhibiting less than ten percent pre-shoot.
