The platform is based on the capabilities of the D2800 Juno Baseband ASIC (BCM21351) – a 65-nm quad-band EDGE/GPRS/GSM multimedia baseband processor with an embedded RF transceiver. Page 5 – 40 COMPANY CONFIDENTIAL Issue 1 Copyright © 2010 Nokia. All rights reserved.
Page 155: Gsm Receiver
The D2800 Juno BB/RF ASIC contains four low noise amplifiers (LNA), one for each band. The receiver uses a low-IF architecture, meaning the incoming RF signal to the mixer is quadrature-down-converted to the IF frequency. Issue 1 COMPANY CONFIDENTIAL Page 5 – 41 Copyright © 2010 Nokia. All rights reserved.
Page 156: Gsm Transmitter
2 dual packages where one is used for low bands (GSM850/GSM900) and the other for high bands (GSM1800/GSM1900). GSM Transmitter The transmit chain consists of the transmitter section of the D2800 Juno’s integrated RF and a dual-mode quad-band FEM.
