Silicon RFIC's for a DCS1800 base station receiver downconverter

This paper describes silicon RFIC's designed for a DCS 1800 base station receiver downconverter. A low-phase noise VCO, a high linearity mixer, and a low-residual phase noise buffer amplifier, all fully integrated in 0.25 um BiCMOS technology, are discussed. Performance of these circuits demonstrated that it is feasible to use low cost silicon technology for base station receiver radios.
