Title: Innovations by James Kyo Long

Introduction

James Kyo Long is an accomplished inventor based in El Cajon, California. He has made significant contributions to the field of microwave circuit packaging, holding two patents that showcase his innovative approach to high-frequency electronic signal transmission.

Latest Patents

One of his latest patents is titled "Ultra-low-loss feedthrough for microwave circuit package." This invention focuses on RF feedthroughs designed for use with monolithic microwave integrated circuits (MMIC). The feedthrough is installed in environmentally protective or hermetically sealed packages that provide electromagnetic shielding. It features a dielectric substrate and a microstrip or transmission line for transmitting high-frequency electronic signals. The wall of the feedthrough has a varying thickness, ensuring that the narrowest portion is positioned above the transmission line, which is also designed with a varying width to minimize parasitic capacitance.

Another notable patent is "High frequency microwave packaging having a dielectric gap." This invention involves a hermetically sealed package assembly for microwave circuits operating at high microwave frequencies. The assembly includes a substrate for carrying the circuit, a seal ring wall, and a via structure for transmitting high-frequency signals. A dielectric gap is strategically placed in the substrate to reduce capacitive coupling between the lead and the wall, enhancing the overall performance of the microwave packaging.
