Introduction

Chang-Ming Lai is a notable inventor based in Chiayi, Taiwan. He has made significant contributions to the field of radio frequency (RF) technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and functionality of RF receiver and transmitter systems.

Latest Patents

One of his latest patents is the "Receiver and transmitter apparatus for carrier aggregation." This invention discloses an RF receiver/transmitter apparatus designed to provide routing circuitry formed by multiple mixer modules. This architecture allows for both carrier aggregation and the mixing frequency process of signals. It improves the degree of integration while reducing hardware costs and power consumption. The apparatus includes at least one antenna, a first signal processing unit, a routing mixer device, a second signal processing unit, and a digital signal processor (DSP). The routing mixer device features multiple mixer modules and current/voltage adders to control signal routing effectively.

Another significant patent is the "Multi-carrier receiver, multi-carrier transmitter and multi-carrier transceiver system." This system includes a first processing unit, a router, and a second processing unit. The first processing unit applies intensity processing on RF signals to output sub-carrier signals. The router connects M input terminals to N output terminals, ensuring that the received signal at each output terminal includes the sub-carrier signal from each input terminal. The second processing unit demodulates the sub-carrier signals and performs analog-to-digital conversion to generate digital signals.
