WiMAX PA Covers 2.3-2.4GHz and 2.5-2.7GHz Bands

SiGe Semiconductor Inc. has expanded its series of power amplifiers (PA) with the release of the SE7271T, a single high-power PA that can cover both 2.3-2.4GHz and 2.5-2.7GHz WiMAX bands. The highly integrated single-die PA is fully matched with a step attenuator, power detector and harmonic filter, all in a 3x3x0.6mm Quad Flat No Lead (QFN) package.

The integrated impedance match combines with the product’s functionality to create a “plug-and-play” solution that both simplifies the design of mobile WiMAX products and improves their manufacturability. The lower current consumption and higher efficiency of the SE7271T reduce current draw and leads to improved the battery life in WiMAX-enabled handsets, mobile Internet devices and laptops.

“Our proven system knowledge and device integration has enabled us to deliver this compact, small footprint PA with unequalled power added efficiency,” says Daniel Ko, Marketing Director, APAC, at SiGe. “WiMAX ultimately stand for freedom and mobility. With the SE7271T’s low current consumption we are delivering the battery life that consumers have come to expect in mobile devices.

“Our competitors struggle with delivering to customers the key value points for the evolution of mobile WiMAX products. Competitive products are physically larger or are not compliant with the temperature range required for data cards and USB dongles. And some don’t cover the complete 2.5GHz WiMAX band. Full 2.3-2.7GHz coverage, increased efficiency at high RF power levels, -40°C to 85°C operating temperature range, reduced package height – these are critical performance areas for mobile WiMAX PAs. The SE7271T delivers on all of them.”
