Title: Innovations of Andrew J Wiebold
Introduction
Andrew J Wiebold is an accomplished inventor based in Marion, IA (US). He holds 2 patents that showcase his expertise in the field of RF technology. His work has significantly contributed to advancements in communication systems.
Latest Patents
One of his latest patents is titled "Automatic phase shifting control loop." This invention discloses a transmitter apparatus and method where an RF terminal provides an RF signal. A first antenna transmits a first portion of the RF signal, while a second antenna transmits a second portion. Directional couplers generate monitoring signals, and a power comparison operational amplifier processes these signals to generate a power difference signal. A phase control operational amplifier then uses this signal to create a phase control signal, which directs the RF signal to the appropriate antenna based on the phase control signal.
Another notable patent is the "Digital power amplifier level control." This invention describes a digital power amplifier with variable output power control. The amplifying stage includes a first attenuator that applies one of several attenuation steps to an RF signal based on the desired output power level. A feedback loop provides a gain control signal to the amplifying stage, ensuring optimal performance.
