Title: David J White: Innovator in Microwave Power Combining Technology

Introduction

David J White is a notable inventor based in Ridgecrest, CA (US), recognized for his contributions to microwave power combining technology. He holds a total of 3 patents, showcasing his innovative approach to engineering challenges in the field.

Latest Patents

One of his latest patents is the "Space Power Combiner," which describes an antenna array designed to combine microwave energy from multiple oscillators, such as IMPATT diodes, through a process of injection locking. This innovative array features elements that are individually driven by the oscillators, with a central element receiving the injection locking signal. The other oscillators are injection locked via mutual coupling, resulting in coherent radiation output by the array. The radiation can be steered using phase shifters positioned between the elements and their respective oscillators.

Another significant patent is the "N-Way Summing Network Characterization System." This system enables quasi real-time computer-aided characterization of symmetrical microwave power combining structures. It employs a network analyzer to measure scattering parameters at various RF frequencies and desired transmission routes through the combining structure. The routes are selected by a coaxial switching network, which is controlled by the network analyzer. This system computes and outputs the maximum combining efficiency and the input impedance of the ith port under conditions of maximum combining efficiency.
