Title: Un Ha Kim: Innovator in Radio Frequency Technology
Introduction
Un Ha Kim is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of radio frequency technology, holding a total of 3 patents. His innovative work focuses on enhancing the performance of power amplifiers and linearizers.
Latest Patents
Un Ha Kim's latest patents include a linearizer and a radio frequency power amplifier. The linearizer comprises a delay compensation circuit, an envelope reshaping circuit, and a phase shift unit. The delay compensation circuit is designed to delay an input signal and output a delayed input signal to a power amplifier. The envelope reshaping circuit detects the envelope of the input signal and generates a reshaped envelope signal. The phase shift unit provides an envelope reshaped capacitance based on the reshaped envelope signal to the delayed input signal, effectively reshaping the delayed input signal.
The power amplifier features a linearized design that includes a first amplification stage with a first transistor for amplifying an input signal and outputting a pre-amplified signal. Additionally, a second amplification stage with a second transistor amplifies the pre-amplified signal. A phase injection circuit, connected to the gates of both transistors, adjusts the phase of the input signal based on the pre-amplified signal to compensate for AM-AM distortion and AM-PM distortion.
