This paper describes a 3 to 5㎓ Sub-Band Generator for UWB (Ultra-Wideband) application using 0.13㎛ CMOS process. The Sub-Band Generator operates in the band group1 whose center frequencies are 3432㎒, 3960㎒, and 4488㎒. To cover the overall frequencies of group 1, an efficient frequency planning minimizing a number of blocks and the power consumption are proposed. The SSB-mixers consume 97㎽ from a 1.5V supply. The die area is 3.3 x 3㎟.
