Latest Patents

One of Kelvin Lee's latest patents is the Switched Capacitor Modulator (SCM). This innovative device includes an RF power amplifier that receives a rectified voltage and an RF drive signal. The modulator is designed to modulate an input signal based on the rectified voltage, generating an RF output signal directed to an output terminal. A unique feature of this invention is a reactance in parallel with the output terminal, which varies in response to a control signal. This capability allows for the adjustment of equivalent reactance, enhancing the performance of the RF power amplifier. The controller within the SCM generates the control signal and a commanded phase, which in turn controls the RF drive signal. The reactance can be either capacitance or inductance, both of which adjust according to the control signal.
