The latest progress made in development of telecommunication networks has enabled data transmissions at higher speeds. Therefore WiMAX technology with data transmission speed of 100Mbps and coverage area of 30 to 50 kilometers has been in focus more than ever before. According to IEEE 802.16-2004 standard, location-fixed WiMAX systems are allowed to utilize frequency band of 3.5GHz. WiMAX mixers have more stringent specification of noise figure than those of other IEEE 802.11 standards and it is essential to obtain both low noise figure and high conversion gain for mixers in WiMAX systems, so design of such mixers is of great importance.
