Introduction

Jon D. Jorgenson is a prominent inventor based in Greensboro, NC (US), known for his significant contributions to radio frequency (RF) technology. With a total of 15 patents to his name, Jorgenson has made remarkable advancements in the field, particularly in the design of circuits that enhance the performance of RF power amplifiers.

Latest Patents

One of Jorgenson's latest inventions is the "Reflection cancellation circuit for a radio frequency power amplifier." This innovative circuit is strategically placed between the output of a power amplifier and downstream circuitry, such as a transmitting antenna. Its primary function is to cancel reflections caused by antenna impedance mismatches, ensuring a constant load impedance is presented to the power amplifier's output. The circuit extracts a portion of the reflected signal, phase-shifts it by 180 degrees, amplifies it to create a cancellation signal, and effectively cancels the remaining reflected signal. This technology is crucial for compliance with total radiated power specifications.

Another notable invention is the "Pilot switch," which is designed to reduce or eliminate arcing between a cantilever contact and a terminal contact in microelectromechanical system (MEMS) switches. The pilot switch circuitry establishes a common potential at the terminals before and after the contacts engage or separate, thereby enhancing the reliability and longevity of MEMS switches.
