Abstract :
A single-chip BiCMOS analog radio for mobile telephony is a strategic utopia today because few foundries provide a BiCMOS technology with sufficient bipolar f/sub T/ for the low-noise mixers in the receiver and transmitter phase modulators and demodulators at 1.9 GHz. The solution presented in this paper is to use an RF silicon bipolar chip for the high frequency circuits of the transceiver and synthesizer and standard low cost CMOS for low-frequency transceiver analog signal processing and synthesizer functions.<>
