描述 Description

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.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.
