Title: Qing Liu’s Wireless Transmitter Innovations.

Introduction

Qing Liu is an inventor based in Suwon, South Korea, whose patent work includes wireless transmitter technology. Liu is associated with Samsung Electronics Co., Ltd. and has 3 patents.

Latest Patents

One of Liu’s latest listed inventions is titled “Transmitter Device and Transceiver Device for Transmitting Different Wireless Standard Signal.” The patent describes a transmitter designed to handle signals that use different wireless communication standards.

In one transmission mode, a power amplifier amplifies a first signal, while impedance circuits help deliver it to a radio-frequency output port. In another mode, a switch routes a second signal through the circuit. Additional switches adjust the impedance circuit’s connection to ground or leave it floating, supporting operation across the two modes.
