Title: The Innovative Contributions of Stephen A. Maas

Introduction

Stephen A. Maas, an accomplished inventor based in Long Beach, California, has made significant contributions to the field of electronic engineering with four patents to his name. His innovative work focuses on enhancing communication technologies, particularly in the realm of ultra-wideband radios.

Latest Patents

One of his latest patents is the "Nonlinear transmission line waveform generator having an input voltage matched to the C/V characteristic of the transmission line." This invention is designed to generate a comb of frequencies and relatively short duration pulses on the order of picoseconds. Such capabilities are instrumental in improving the bandwidth of ultra-wideband radios, potentially increasing frequencies up to hundreds of GHz. The key aspect of this invention lies in matching the ΔC/ΔV characteristics of the transmission line with the input sinusoidal waveform, enabling it to function effectively as a harmonic generator and produce short duration pulses as needed.

Another noteworthy patent is the "Wideband low-loss variable delay line and phase shifter." This programmable phase shifter employs a nonlinear transmission line, allowing it to adapt to variations in input signal frequency. By utilizing a variable DC bias, the phase velocity and delay of the nonlinear transmission line can be modified, thus changing the input voltage standing wave ratio (VSWR). The invention also demonstrates versatility with options to integrate hybrid couplers or power splitters to minimize distortion.
