Title: Niels-Henrik Lai Hansen: Innovator in Power Amplifier Technology
Introduction
Niels-Henrik Lai Hansen is a prominent inventor based in Frederiksberg, Denmark. He has made significant contributions to the field of telecommunications, particularly in the development of advanced power amplifier technologies. With a total of 5 patents to his name, Hansen continues to push the boundaries of innovation in his field.
Latest Patents
Hansen's latest patents include a "Feed-forward power amplifier with offline tuning capability." This invention describes a method and base station transmitter designed to provide offline tuning of a base station transmitter. The base station transmitter features a feed-forward power amplifier with a Radio Frequency (RF) input and an RF output. Additionally, it includes a simulated carrier generator that is operatively coupled to the feed-forward power amplifier prior to the carrier cancellation loop. This generator provides a simulated carrier signal that includes one or more individual carrier frequencies to the RF input. The system also incorporates a processor that is operatively linked to both the feed-forward power amplifier and the simulated carrier generator. This processor performs tuning of a carrier cancellation loop using the simulated carrier signal when it determines that a carrier signal is absent.
Another notable patent is the "Apparatus and method for operating a transmitter." This invention outlines a linear transmitter that includes a closed loop feedback path to maintain the linearity of a power amplifier subsystem. The closed loop feedback path facilitates RF injection of one or more reference RF carrier signals combined with a radio frequency (RF) feedback signal to generate a feedback RF error signal. A narrowband receiver continuously monitors the stability of this feedback RF error signal. Furthermore, a loop phase adjusting circuit generates phase adjustments to compensate for instabilities in the closed loop feedback path, thereby ensuring the stability of the PA RF output signal.
