Title: Joung-hoe Kim: Innovator in RF Technology

Introduction

Joung-hoe Kim is a prominent inventor based in Hwaseong-si, South Korea. He has made significant contributions to the field of radio frequency (RF) technology, holding a total of 7 patents. His innovative designs focus on improving the efficiency and functionality of RF connectors and filters.

Latest Patents

One of Kim's latest patents is an RF connector capable of processing signals in various frequency bands. This connector features a first printed circuit board with mounted devices and a first bridge assembly that includes signal transmission pins. It also has a second printed circuit board spaced apart from the first, with connection terminals that contact the surfaces of the signal pins. A push bar applies force to maintain contact between the pins and terminals, while a metal shielding plate is fixed to the push bar and second board, providing necessary shielding. This design allows the connector to transmit RF signals, power, and digital signals on the same plane, effectively reducing size and cost while processing signals across various frequency bands without the need for expensive multi-connectors.

Another notable patent is a cavity filter assembly that includes an RF filter with an empty area formed between the RF filter and a cavity filter body. This design reduces parasitic capacitance and improves frequency characteristics, particularly in low-pass filters. The cavity filter body is designed with a first pocket portion for the RF filter and a second pocket portion that overlaps a transmission line, which helps in reducing insertion loss and positioning harmonics further away from the cutoff frequency.
