Ramp-up of first SiGe circuits for mobile communications:positioning of SiGe vs. GaAs and silicon

摘要

This paper reviews the current competition and potential of GaAs,SiGe and Si components in DECT, GSM, CDMA and PDC wireless communicationsystems. Results of the first products designed in a SiGe bipolartechnology, e.g. dual band low noise amplifiers and PLL prescalers, arepresented
