Latest Patents

One of Gregory French's latest patents is titled "Amplification system having mask detection." This invention focuses on reducing the out-of-band frequency components of an RF amplified signal, particularly for CDMA signals with unknown carrier frequencies. The method involves locating the frequency of the incoming signal by analyzing an RF output signal that contains both in-band and out-of-band frequency components. The output signal is typically generated using a high-power, Class A/B amplifier. Once the carrier frequency is determined, control signals are generated to minimize the energy of the out-of-band signals, resulting in a more linear amplifier transfer function.

Another notable patent by French is "Amplification system having mask detection and bias compensation." This invention also aims to reduce out-of-band frequency components of RF signals with unknown carrier frequencies. It employs a control signal to adjust the bias parameters of the circuit. In specific embodiments, the RF signal is produced from a MOSFET power amplifier, which can introduce distortion components into its output. By varying the bias parameters of the MOSFET amplifier, out-of-band distortion can be minimized, enhancing the overall signal quality.
