Abstract

SS radio communication systems in 2.4 GHz ISM band, such as IEEE802.11 and Bluetooth are widely known. These systems can provide very high data rate, over several Mbps. However, on the other hand, they have problems such as high current consumption, short range service area, large size, high design expenditure and development difficulty. From the view point above, to solve these problems, we developed an ultra low current consumption 2.4 GHz DSSS radio modem, which consumes 35 mA current at full rate, in a small size and for a wide service area. Although the current consumption was extremely low, the receiver sensitivity and intermodulation-distortion performance were qualified. A sufficient performance was obtained from actual measurement of the system.
