Latest Patents

Among his most recent patents, Choi has developed a sophisticated front-end module that incorporates a substrate with first and second connection members alternately stacked with insulating and wiring layers. This module features a core member positioned between these connection members, to enhance signal processing capabilities. It includes a radio-frequency component designed to amplify the main band of an input RF signal while filtering out unwanted bands. Additionally, it employs an inductor connected to the radio-frequency component and a ground plane situated on another surface of the core member, which has an insulating layer thicker than those used in the connection members.

Another notable invention is a power amplifying apparatus featuring a bias boosting structure that improves linearity. This apparatus utilizes a first bias circuit to create a first bias current by adding a boost current to a base bias current derived from a reference current. It enhances signal output by employing a first amplification circuit and integrates a bias boosting circuit to generate the necessary boost current based on the harmonic components of the amplified signal.
