INTEGRATED CIRCUITS DATA SHEET UAA3535HL Low power GSM/DCS/PCS multi-band transceiver Objective specification File under Integrated Circuits, IC17 2000 Feb 17 Philips Semiconductors Objective specification Low power GSM/DCS/PCS multi-band transceiver FEATURES Multi-band application for GSM, DCS and PCS cellular phone systems Low noise and wide dynamic range low IF receiver More than 35 dB on-chip image rejection in receive mode More than 64 dB gain control range in receive mode Integrated channel filter Integrated TX low-pass filter High precision I/Q modulator Multi-band TX modulation loop architecture including offset mixer and phase-frequency detector Dual PLL with on-chip fully integrated IF VCO Fully differential design minimizing crosstalk and spurious signals Functional down to 2.4 V and up to 3.6 V 3-wire serial bus interface LQFP48 package. APPLICATIONS GSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz hand-held transceivers. GENERAL DESCRIPTION The UAA3535HL is intended for Global Systems for Mobile communication (GSM), Digital Cellular communication Systems (DCS) and Personal Communication Services (PCS). The circuit integrates the receiver and most of the transmitter section of hand-held transceivers for these applications. The receiver consists of two sections. The first section is the RF receiver front-end, which amplifies the GSM, DCS or PCS aerial signal, then converts the chosen channel down to a low Intermediate Frequency (IF) of 100 ...
