Novatel selects Anadigics’ PAs for HSPA+ mobile broadband USB modems

Anadigics Inc of Warren, NJ, USA, which provides radio frequency integrated circuit (RFICs) for the broadband and wireless communications markets, says that wireless broadband solutions provider Novatel Wireless Inc of San Diego, CA has selected its WCDMA/HSPA and EDGE power amplifiers (PAs) for two new wireless HSPA+ mobile broadband USB modems.

HSPA+ is the next evolution of high-speed packet access (HSPA) wireless broadband technology, offering data rates of 14.4–28Mb/s (with the potential to achieve 42Mb/s on a 5MHz carrier) versus early 3G networks delivering 384kb/s data.

Novatel’s Ovation MC996D and MC998D wireless broadband USB modems give laptop PC and notebook users upload speeds as high as 5.76Mb/s and download speeds of 21.6Mb/s or higher on HSPA+ networks, enabling high-quality video, multimedia, gaming and other data-intensive mobile applications. Anadigics says that its PAs deliver the power and linearity required for high-speed uplinks in EDGE, WCDMA, HSPA, and HSPA+ modes.

Both Novatel Wireless modems have received industry compliance from the Global Certification Forum (GCF), involving several hundred product lab test cases and extensive field trials that measured their performance on different 3G networks in Europe. The testing ensures that the MC996D and MC998D will have the highest reliability and functionality on HSPA+ mobile networks worldwide, says Anadigics.

The MC996D operates in 3G modes in the 2100MHz and 900MHz UMTS bands widely used in Europe and also includes quad-band EDGE for connectivity on GSM/EDGE networks around the world. The MC998D operates in 3G modes in the 2100MHz, 1900MHz and 850MHz UMTS bands used in North America and Japan, and also includes quad-band EDGE connectivity. Novatel selected Anadigics’ AWT6222 and AWT6224 dual-band PAs for WCDMA, HSPA and HSPA+ operation, and its AWE6159 quad-band PA for EDGE mode operation.

Anadigics’ AWT6222 and AWT6224 are dual-band HELP3 WCDMA/HSPA power amplifiers that incorporate the firm’s proprietary technology for high efficiency at low power, while delivering the high output power and linearity required for high-rate, low-BER uplink transmissions in HSPA and HSPA+ modes. The products incorporate separate amplifier chains for two UMTS bands in a single 3mm x 5mm package, with common power and logic connections to reduce RF board area and simplify layout.

Anadigics’ AWE6159 quad-band EDGE PA is designed to meet performance requirements for GMSK and EDGE modes chipsets using open-loop polar modulation, such as the Qualcomm MDM8200. It has an internal reference voltage and integrated power control for both GMSK and 8PSK operation to reduce the number of external components and to simplify production calibration. The AWE6159’s power control function includes battery detection circuitry for robust ORFS transient spectrum performance at low battery voltages. Its 5mm x 5mm package is 49% smaller than Anadigics’ previous generation of polar-EDGE devices.

A recent survey by the Global mobile Suppliers Association (GSA) confirmed 315 WCDMA networks in operation at the end of 2009, of which 303 networks also offered HSPA service in operation (delivering subscribers data rates of 3.6Mb/s or higher). The GSA also confirmed 37 commercial HSPA+ networks in service, including systems in Australia, Europe and Asia. Another 29 operators around the world have committed to deploy HSPA+ in 2010 or 2011.
