3. TECHNICAL BRIEF 3.1 GENERAL DESCRIPTION The LG-P970 supports UMTS-900, UMTS-1900, UMTS-2100, GSM-850, GSM-850, GSM-900, GSM-1800, and GSM- 1900 based GSM/GPRS/EDGE/UMTS. All receivers and the UMTS transmitter use the radioOne1Zero-IF architecture to eliminate intermediate frequencies, directly converting signals between RF and baseband. The quad-band GSM transmitters use a baseband-to-IF upconversion followed by an offset phase-locked loop that translates the GMSK-modulated or 8-PSK-modulated signal to RF.
Page 26 PA, the complete loop circuits are implemented in the digital domain, which enables a high reliability of the loop performance for both standards. LGE Internal Use Only - 6 - Copyright © 011 LG Electronics. Inc. All right reserved. Only for training and service purposes...
Page 27 The AFC control is maintained by providing a voltage generated by a 12-Bit DAC to the external TCVCXO module, which means the reference clock is synchronized to the system frequency.
