INTEGRATED CIRCUITS DATA SHEET UAA3522HL Low power dual-band GSM transceiver with an image rejecting front-end Objective specification File under Integrated Circuits, IC17 2000 Feb 18 Philips Semiconductors Objective specification Low power dual-band GSM transceiver with an image rejecting front-end FEATURES Dual-band application for Global System for Mobile communication (GSM) and Digital Cellular communication Systems (DCS) Low noise and wide dynamic range single Intermediate Frequency (IF) transceiver More than 30 dB on-chip image rejection in the receiver More than 60 dB gain control range I/Q demodulator with high performance integrated baseband channel filter High precision I/Q modulator Transmit modulation loop architecture including offset mixer and phase detector Dual Phase-Locked Loop (PLL) with on-chip IF Voltage Controlled Oscillator (VCO) Fully differential design minimizing cross-talk and spurii 3-wire serial bus interface Functional down to 2.7 V and up to 3.3 V LQFP48 package. APPLICATIONS GSM 900 MHz hand-held transceiver GSM/DCS dual-band solution with the UAA2077CM (down to 3.2 V) or UAA2077TS/D (down to 2.7 V). GENERAL DESCRIPTION The UAA3522HL integrates the receiver and most of the transmitter section of a GSM hand-held transceiver. It also integrates the receiver IF and the transmitter section of a DCS transceiver. The receiver comprises an RF and an IF section. The RF (GSM) front-end amplifies the aerial signal, converts ...
