iSR1500 Series

GSM/GPRS Module

Data Sheet

1 Introduction

1.1 General Description

iSR1500 series is a product line of single-module platform optimized

for ultra low cost GSM handsets and GPRS modem. It integrates all

the functions necessary for a dual-band GSM/GPRS mobile handset,

including baseband, mixed signal, power amplifier, power

management, RF transceiver, front-end switch and memory in a

single monolithic module.

The highly integrated module simplifies handset design, and is

capable of working on 2-layer motherboard with no further RF

calibration required.
