Title: James Andrew Martin, III: Innovator in Tunable Microwave Devices

Introduction

James Andrew Martin, III is a notable inventor based in Londonderry, NH (US). He has made significant contributions to the field of microwave technology, holding 2 patents that showcase his innovative approach to dynamic impedance matching networks.

Latest Patents

One of his latest patents is focused on tunable microwave devices with an auto-adjusting matching circuit. This invention provides an apparatus that includes an input port and a dynamic impedance matching network. The network is capable of determining a mismatch at the input port and dynamically changing the RF match using at least one matching element, which includes a voltage tunable dielectric capacitor. The matching network can be a 'Pi', 'T', or “ladder” type network. Additionally, the apparatus may comprise at least one directional coupler that collects signals by sampling a portion of an incident signal, a reflected signal, or both. The invention also includes a control and power control & logic unit (PC LU) that converts input analog signals into digital signals, senses VSWR phase and magnitude, and processes the digital signals using an algorithm to provide a voltage value. These voltage values can then be compared to values from the coupler, and once matched, they are passed to a High Voltage Application Specific Integrated Circuit (HV ASIC) to distribute compensatory voltages to the matching network elements.
