Anadigics Inc. brings to market a new 5GHz WLAN power amplifier (PA) that was developed to increase both range and data throughput for demanding, high-data rate applications. The AWL9555 is suited for applications including the wireless transmission of HD video between residential gateway devices and televisions, routers offering 802.11a/n Wi-Fi connectivity, and portable devices such as notebook PCs, netbooks and handsets that offer dual-band WLAN connectivity.

Enhanced multimedia applications such as streaming HD video require high data rates and robust signals, a combination that increases the demand for spectral bandwidth. Anadigics' AWL9555 power amplifier enables OEMs to take advantage of the broad bandwidth available in the 5GHz unlicensed spectrum around the world. The AWL9555 provides high linearity and high output power over the full 5GHz band, enabling OEMs to deliver high-quality video and high speed data wirelessly over a greater distance.

"Consumer demand for wireless connectivity everywhere is increasing, and now the trend is turning toward high data rate connectivity throughout the home for high performance video gaming, access to HD video, and even high speed Internet access in the yard," stated Glenn Eswein, director of product marketing for Anadigics. "Groups such as the WHDI consortium are a driving force behind the integration of wireless connectivity into home entertainment systems, and Anadigics has leveraged its RF power amplifier expertise to develop a device that enables OEMs to meet the high expectations of today's multimedia-savvy consumer."

WHDI is an emerging application that has strong support from leading OEMs including Samsung, LGE, Hitachi and Sharp. With the proliferation of WHDI, manufacturers of cable boxes and home gateway devices can use the AWL9555 power amplifier to provide the range and signal quality needed to deliver wireless HD video to televisions throughout the home. As a result, consumers can enjoy crystal-clear streaming video without the need for unsightly cables.

The AWL9555 is a highly integrated, RF-matched device that reduces overall component count and is easy to design into new equipment platforms. Its low profile 3mm x 3mm x 0.55mm package makes the AWL9555 a good choice for size-constrained mobile applications such as handsets which, according to ABI Research, are forecasted to drive strong growth in the Wi-Fi market.

Technical specifications include 4.9- to 5.85GHz operation; 2.5 percent dynamic EVM at +19dBm output power; 175mA supply current at +19dBm output power; 29dB of linear power gain; 3.3V supply; Integrated power detector with 20dB dynamic range; 50? internally matched RF ports.

The RoHS-compliant Anadigics' AWL9555 WLAN PA measures 3mm x 3mm x 0.55mm in a Pb-free package. It is available now at $1.57 each in quantities of ten thousand.
