Latest Patents

One of Jung-Rin Woo's latest patents is a power amplifying apparatus. This apparatus includes a radio frequency (RF) power amplifier, a supply modulating unit, a phase shifting unit, and an envelope shaping unit. The RF power amplifier receives an input RF signal and outputs an amplified RF signal. The supply modulating unit provides the RF power amplifier with a supply voltage that varies with the original envelope of the input RF signal. The phase shifting unit receives a control signal and shifts the phase of the input RF signal to be inputted to the RF power amplifier by a shift amount that varies with the control signal. The envelope shaping unit receives the original envelope and provides the phase shifting unit with the control signal, which varies with the original envelope.

Another notable patent is the pulsed dynamic load modulation power amplifier circuit. This power amplifier circuit is designed for amplifying an envelope modulated RF signal with improved linearity and efficiency. It includes a power amplifier and a variable load matching circuit coupled to the output port of the power amplifier. The input impedance of the variable load matching circuit is changed such that the output power of the power amplifier is at a first output power level or a second output power level, which is higher than the first output power level.
