A Monolithic CMOS Radio System for Wideband CDMA Communications

this paper, we will focus primarily on the broadbanddownlink, given the high data rates, the need for lowpower consumption, and size in the portable unit. Theoverall system design, the analog RF circuitry, and the digitalbaseband circuitry will be discussed, particularlyemphasizing a single-chip, silicon CMOS solution for themobile receiver.I.
