Abstract
A direct up-conversion transmitter IC for reconfigurable multi-band/multi-standard base stations is presented. It was manufactured in a 0.35 µm 75 GHz fT SiGe BiCMOS process. The chip consists of a quadrature modulator, an integrated baseband filter, and a reconfigurable prescaler which includes the quadrature signal generation and provides three different divider-ratios for a reduction of the VCO tuning range. The up-converter was designed for a frequency range of 400 MHz up to 2.7 GHz. Measurements show an maximum output channel power of -1.9 dBm and an ACLR lower than -57 dBc. The measured EVM is lower than 2.2% and the noise floor has an upper limit of -153 dBm/Hz.
