1 Introduction
1.1 General Description
iSR3500 series is a product line of single-module platform optimized for
ultra low cost GSM/GPRS modem and generic mobile applications. It
integrates all the functions necessary for a dual-band GSM/GPRS w ireless
communication, including baseband, mixed signal, p ower amplifier, power
management, RF transceiver, front-end switch and memory in a single
monolithic module with board-to-board connector
The highly integrated module is ideal for application requiring GSM, and is
capable of working on 2-layer motherboard with no further RF calibration
required.
