abstract

  • This first commercially available CMOS CDMA transmitter IC is based on a zero-IF architecture and designed for US/China/Korea and Japan cellular bands. The transmitter IC integrates direct upconverter, VGA, driver amplifier, VCO, and both transmit and receive PLLs in 0.24 /spl mu/m CMOS. The chip provides more than 100 dB power control range and consumes 57.5 mA at 2.6 V with +6 dBm output power and -51.7 dBc ACPR.
