Product Description

U7309 is a wireless module which is designed for the global market. It is a consumptive product; it can be designed in many kinds of applications which can work on HSPA+/UMTS/EDGE/GPRS/GSM network.


U7309 support the Bands as the following:

Triple-Band UMTS(HSPA+): 850/1900/2100 MHz;

Quad-Band GSM: 850/900/DCS1800/PCS1900 MHz


On HSPA network in the world, U7309 enables connect to the Internet at DL data speed up to 14.4Mbps and UL data speed up to 5.76Mbps. In areas where HSPA service is not available, U7309 still enables reliable and secure data connections over UMTS at speed up to 384 Kbps or EDGE at speed up to 237Kbps or GPRS at speed up to 85.6Kbps.


U7309 provides Audio, SMS, Phonebook functions as well as high speed access. It can be designed in many kinds of applications. Such as Data card, Video monitor, Tablet, Electric-book, MID, Vehicle equipment, etc.


U7309 integrates the RF and Baseband onto one small PCB. It can fulfill all the functions of RF signal receiving and transmitting, Baseband signal processing and audio signal processing so that the customers can realize all kinds of their own wireless products with very few peripheral components.


Designed on a Dual-side PCB, U7309 has a tiny dimension of 50.85mm×29.9mm×4.6mm, with a PCI express mini card connector, which provides all hardware interfaces between the module and customers’ boards. The main hardware interfaces of U7309 consist of power supply interfaces, USB interface, UART interfaces, USIM/SIM interface, Audio interfaces, PCM interface, IIC interface, VRTC interface and GPIO. Consider connecting antenna, U7309 provides 2 plug-in RF connectors.


U7309 is integrated with the TCP/IP protocol, it not only supports standard AT but also supports Longsung extended AT commands, which are very suited for developing all kinds of the customized applications.
