Title: Kwang-Ho Ahn: Innovator in RF Vector Modulation

Introduction

Kwang-Ho Ahn is a prominent inventor based in Yongin-si, South Korea. He has made significant contributions to the field of radio frequency (RF) technology, particularly in the area of beamforming.

Latest Patents

One of his notable patents is the "RF vector modulator for beamforming." This invention includes a first amplification part that amplifies an input single RF signal and outputs differential RF signals of different phases. The RF signal converter receives these differential RF signals and outputs four signals: I+, I−, Q+, and Q−, each with different phases. The RF signal converter features a polyphase filter that is virtually opened by resonance of an output terminal comprising a transmission line load. Additionally, the invention includes a Variable Gain Amplifier (VGA) part that varies the amplitude and polarity of the signals I+ and I−, as well as Q+ and Q−, according to a control signal. Finally, an RF signal synthesizer synthesizes the output currents of the I VGA and Q VGA.
