Qualcomm specifies Anadigics’ PAs

RFIC maker Anadigics Inc says its WCDMA and GPRS/EDGE power amplifiers (PAs) have been specified by Qualcomm for the Mobile Station Modem (MSM) MSM7200 and MSM6280 chipset reference designs.

MSM7200 supports the high-speed uplink packet access (HSUPA) standard for peak data rates of 7.2 Mbps on the downlink and 5.76 Mbps on the uplink, whereas MSM6280 supports the HSDPA standard for enhanced peak downlink rates of up to 7.2 Mbps.  HSDPA and HSUPA allow users to achieve wireless broadband speeds that rival wired connections.

Qualcomm's MSM7200 reference design specifies Anadigics' WCDMA and EDGE PAs to support eight frequency bands.  The four WCDMA frequency bands are enabled by Anadigics' AWT6273, AWT6278, AWT6279, and AWT6282 PAs, while the four EDGE frequency bands are supported by the company’s AWT6280 polar EDGE PA. The MSM6280 reference design specifies Anadigics' AWT6273, AWT6278 and AWT6279 WCDMA PAs, as well as the company’s AND0041 quad-band polar EDGE PA.

Anadigics' AWT6273, AWT6278 and AWT6279 WCDMA PAs utilize the company’s 3G High-Efficiency-at-Low-Power (HELP3) technology. HELP3 WCDMA PAs offer full compliance with HSDPA and HSUPA requirements, while reducing average current consumption by 75% compared with a conventional power amplifier, says Anadigics. The PAs provide quiescent currents of 7 mA without a DC-DC converter, and eliminate the requirements for external voltage regulation. This is achieved by using a patented InGaP- Plus technology, which combines bipolar and field-effect transistor (FET) devices on the same InGaP GaAs die.

"As mobile manufacturers develop advanced 3G devices to take advantage of the data speeds enabled by HSDPA and HSUPA networks, battery life becomes a critical concern. Anadigics' industry-leading HELP3 WCDMA power amplifiers have been optimized not only to deliver excellent voice clarity and data integrity, but also to significantly improve the operating time of 3G devices," said Dr. Bami Bastani, president and CEO of Anadigics.
