UMC Develops RF Chip for WiMax with National Taiwan University

UMC has partnered with National Taiwan University (NTU) to develop a high performance, fully integrated RF receiver design for WiMax. The low noise amplifier in the 0.18um RF receiver has demonstrated the low noise figure of 1.78dB in a 5 GHz range. The receiver radio frequency front end with ultra low operating voltage (1 volt) also achieved a low noise level of 5-6 dB. In addition, by adopting a new type of system architecture, the design effectively suppresses the DC offset resulting from direct conversion receivers well below noise levels. This design will be packaged as an IP for commercial applications.
