			ACE Technology started its business in 1980 manufacturing car phone antennas. Ever since then, ACE’s employees, now numbering more than 680 including 130 engineers, have been working toward the advancement of the wireless industry. ACE Technology had been developing antennas and RF components for wireless and satellite communications. Now ACE’s technical expertise encompasses all areas of wireless communications. ACE not only has developed and marketed base station antennas for digital cellular telephones, RF components, power amplifiers, and repeater systems, but also has become a Total Solution Provider of communications and information technologies providing such services as signal and cell site optimization for network design. Leveraging its core technology, ACE also developed high-gain omni-directional and directional antennas for PCS, RF components such as Tx and Rx bandpass filters, RF switches, step attenuators, ceramic combiners using high-Q dielectric resonators, and Cellular and PCS repeater systems with anti-interference capabilities using ICS technology. ACE also contributed to the advancement of competitiveness in the Korean communication’s technology industry through their efforts in research and development. In addition, ACE has successfully completed several research projects. These include “Development of technology to design and manufacture filters for satellite broadcasting and communications” and “Development of highly efficient power amplifiers for mobile communication base stations”, commissioned by the Ministry of Industry and Natural Resources in its effort to develop an industrial infrastructure. In carrying out these research projects, ACE Technology gained technical expertise and experience in manufacturing RF component such as bandpass filters, duplexers, cavity filters, circulators, isolators, and high-efficiency, high-gain antennas. ACE Technology is currently working with Korea’s wireless system providers in developing RF components for PCS and CDMA wireless mobile systems. Through our efforts to sharpen international competitiveness and increase overseas business, we have acquired many international customers. We are supplying major international telecommunications companies with our RF components. At present, we have completed basic research of the emerging IMT-2000 World Standard, preparing for the demand by system providers, both domestic and abroad.

			ACE TECHNOLOGY, as a global leader in the information and communications industry, has been consistently investing from 20 to 25% of its annual revenues in Research and Development in order to provide state of the art products. A total of 110 researchers, which represent about 1/4 of our total work force, including 21 with Ph.D. and Master's degrees are conducting research in the areas of our core products and systems. Our researchers are doing their utmost in development of state of the art technology and continued customer satisfaction. The R & D Lab is divided into four sections: Section 1 develops base-station and portable antennas, Section 2 develops passive RF components and systems, Section 3’s efforts center around repeater systems and other active RF components and systems, and the fourth is Research Planning, which oversees technical marketing, research planning, and various certifications.
