Abstract

A direct conversion 0.4/spl mu/m SiGe BiCMOS transmitter and receiver PLL consists of two transmitters, two PLLs, and an integrated VCO for cellular, PCS/IMT and GPS applications. The chip consumes 71mA at 2.7V with -55dBc ACPR at 885kHz offset and -134dBm/Hz noise at 45MHz offset for cellular, and 79mA, -56dBc ACPR at 1.25MHz offset, and -132dBm/Hz noise at 80MHz offset for PCS.
