Anadigics’ new InGaP family supports E-UTRA Band
The devices are manufactured using the firm’s advanced indium gallium phosphide HBT MMIC technology
The company’s small-cell wireless infrastructure PA family delivers a combination of high output power, efficiency, and linearity and are optimised for the rapidly growing class of small-cell base stations.
The two new power amplifiers (PAs), the AWB7128 and AWB7228, are optimised for WCDMA, HSPA, and LTE base stations.
The AWB7128 provides +24.5 dBm linear output power, while the AWB7228 delivers +27 dBm linear output power. These power amplifiers use Anadigics’ InGaP-Plus technology to achieve best-in-class efficiency and linearity at these output power levels, enabling small-cell wireless infrastructure solutions that are more thermally- efficient, consume less power, and provide a greater range.
Anadigics’ AWB7128 and AWB7228 PAs have a linearity of -47 dBc ACPR @ +/- 10 MHz offset (10 MHz channel bandwidth).
The modules, which come in a 7 mm x 7 mm x 1.3 mm surface mount package are optimised for operation in a 50 Ω system.
Triquint annual net income plummets 75%
The firm has suffered from reduced “Defence and Aerospace” and the “Networks” product demand. Revenues for these sectors were down 9% and 4% respectively from 2010 to 2011
“The continual increase in consumer demand for wireless data is fuelling the rapid deployment of small-cell wireless infrastructure devices, such as picocells and femtocells,” said Glenn Eswein, director of product marketing for broadband RF products at Anadigics.
“Anadigics’ small-cell power amplifier family delivers the highest output power, power-added efficiency, and linearity in its class, enabling manufacturers to develop compact, aesthetic, high throughput devices that offer service providers an economical path to expand broadband network coverage. Working closely with device manufacturers, we are expanding this family to help bring the same performance and design flexibility to additional frequency bands.”
The AWB7128 and AWB7228 wireless infrastructure PAs are optimised for WCDMA, HSPA, and LTE small-cell base stations operating in the 2620 MHz to 2690 MHz frequency band.
RF product innovator TriQuint Semiconductor has announced its financial results for the quarter and year ended December 31, 2011.
Revenue for the fourth quarter of 2011 was $227.0 million, down 10% from the fourth quarter of 2010 and up 5% sequentially. Revenue for 2011 was $896.1 million, up 2% from 2010. Mobile Devices revenue grew 7% sequentially and 6% for 2011 compared to 2010.
GAAP gross margin for the fourth quarter of 2011 was 29.5%, down from 34.9% in the prior quarter. Gross margin for the year ended December 31,
