u-blox N731 UMTS/HSPA Modem Reference Design
u-blox announced the N731 UMTS/HSPA modem reference design. The high-speed wireless connectivity reference design features full High-Speed Packet Access (HSPA) capabilities: 7.2 Mb/s download and 5.8 Mb/s upload speeds. The N731 is a design that combines a baseband processor, RF transceiver, antenna multiplexer, and power amplifier components to support eight bands of HSPA / UMTS / EDGE / GPRS / GSM functionality including data, voice, and SMS.
The N731 reference design is available for license to OEM customers for high volume applications. It requires only 35.7 x 24.0 x 2.5 mm of PCB area.
