Abstract :
A single-chip solution for a GSM 900-MHz RF TX quadrature modulator and RX quadrature demodulator is designed and fabricated in a 9-GHz silicon bipolar technology. The transmit modulator is a direct upconverter and the receive demodulator operates in a zero IF architecture. This device is a component of a pocket-size hand-portable phoneset for application in the GSM pan-European digital mobile radio system. The consumption from the battery is 25 mA in RX mode and 45 mA in TX mode. The circuit is powered from a 5-V regulated supply voltage
