Title: Joe Archambault: Innovator in RF Signal Amplification
Introduction
Joe Archambault is a notable inventor based in San Diego, CA. He has made significant contributions to the field of radio frequency (RF) signal amplification. With a total of 2 patents, Archambault's work focuses on enhancing the efficiency of amplifying wideband envelope signals.
Latest Patents
One of Archambault's latest patents is an apparatus and method for efficiently amplifying wideband envelope signals. This innovation involves systems and methods for amplifying an RF input signal by utilizing a moderately power-efficient wide bandwidth device, such as an AB-type amplifier. This device amplifies the power in the high-frequency components of the input signal. Additionally, a highly power-efficient narrow bandwidth device, like a synchronous buck DC/DC converter, is employed to amplify the power in the low-frequency components. The amplified low and high-frequency components are then combined to produce an amplified replica of the RF input signal. To ensure stability, a positive feedback loop is established between the output of the AB-type amplifier and the input of the DC/DC converter. Furthermore, a negative feedback loop is implemented between the output of the DC/DC converter and the input of the AB-type amplifier to minimize interference introduced by the DC/DC converter.
