Anadigics’ InGaP PA Maximises Wireless Network Connectivity
The firm says its AWB7227 power amplifier (PA) delivers exceptional output power, linearity and efficiency. It is best suited for use in femtocells, picocells and other small-cell infrastructure equipment.
Responding to rising market demand for femtocell and picocell technology, Anadigics has introduced a new highly linear and efficient power amplifier (PA), the AWB7227.
Designed to enable a new class of wireless infrastructure equipment, the AWB7227 extends Anadigics’ portfolio of PAs for use in small-cell base stations, which are rapidly growing in popularity among service providers as an effective way to expand wireless network capacity and coverage.
The firm says its AWB7227 PA has exceptional linear output power and high efficiency, and supports WCDMA, HSDPA and LTE air interfaces operating in the 2.11 GHz to 2.17 GHz band. Complementing other PAs in the Anadigics AWB family, including the AWB7127 and AWB7123, the AWB7227 delivers +27 dBm of WCDMA power with an ACPR better than -50 dBc and 14% power-added efficiency.
Such performance enables femtocells and picocells with further reach and smaller, more thermally-efficient designs. Manufactured using an advanced InGaP HBT MMIC technology the device combines temperature stability with ruggedness.
It comes in a 7 x 7 x 1.3 mm surface mount package incorporating RF matching networks optimised for output power, efficiency and linearity in a 50 Ω system and supports multi-carrier operation in E-UTRA downlink operating Band I.
“Femtocells and picocells are a smart and cost-effective way to provide ubiquitous wireless coverage for end users,” said Joe Cozzarelli, Senior Director, Broadband RF Products, Anadigics. “As more service providers adopt small-cell base station technology, we anticipate strong demand for PAs like the AWB7227, which provide flexibility in network architectures by delivering high linearity, output power, efficiency and reliability.”
Leading wireless market analysts, as well as industry organisations such as the Femto Forum, are projecting significant expansion for the femtocell/picocell market. Published reports predict femtocell shipments over the next three years to reach nearly 50 million units. In addition, the market for femtozone services, which include mobile voice and data applications triggered when a device comes within range of a femtocell, is expected to reach nearly $2 billion in revenue by 2015.
Engineering samples of the AWB7227 PA are available now for qualified opportunities.
The AWB7227 is one of the new Anadigics products being promoted at the 2011 Mobile World Congress, February 14-17 in Barcelona, Spain at STAND2C19, Hall 2.
