Latest Patents

One of his latest patents is a "Power amplifier and gain reduction circuit thereof." This invention includes a gain attenuation circuit that receives an input signal, an external drive signal, and a bias voltage. It outputs a secondary input signal after attenuating the input signal based on the drive signal and bias voltage. The amplifier features a bias input terminal for receiving a bias voltage, a signal input terminal for the secondary input signal, and an output terminal for the gained output signal. This power amplifier gain attenuation circuit effectively reduces gain while minimizing phase jump caused by the attenuation.

Another notable patent is the "Multi-mode multi-frequency power amplifier." This invention comprises a controller, a wide-band amplifier channel, and a fundamental impedance transformer. The controller receives an external signal and outputs a control signal accordingly. The wide-band amplifier channel processes single-band or multi-band RF signals, amplifying them and outputting the RF signals through the output terminal. The fundamental impedance transformer includes shared and specialized segments for RF signals across all bands, along with a switching circuit controlled by the controller for multiplexed outputs.
