Enhancement mode GaAs pHEMT LNAs for ISM band and cellular infra applications

Skyworks Solutions, Inc. has unveiled two new series of Low Noise Amplifiers (LNAs) for multiple industrial, scientific, medical (ISM) bands and cellular infrastructure applications.

“Skyworks’ suite of solutions highlights our continued focus on broad market, low noise amplifier products for performance driven customer applications,” said Liam K. Griffin, executive vice president and general manager of high performance analog at Skyworks. “Our products leverage Skyworks’ strength in GaAs pHEMT design technology as well as our high volume, low-cost multi-chip module assembly capabilities - - - two key differentiators within our analog portfolio.”

The SKY67012-396 LF (300 – 600 MHz), SKY67013-396LF (600 – 1500 MHz) and SKY67014-396LF (1500 – 3000 MHz) and SKY67015-396 LF (30 – 400 MHz) are suggested as ideal low noise amplifiers for battery powered receivers in applications such as wireless metering and security, public safety radio, wireless microphones and Bluetooth headsets. The supply voltage is adjustable over a wide 1.8 to 5V range and draws a current of 5 mA. The LNAs are manufactured in a miniature, 2 x 2 mm restriction of hazardous substances compliant, surface mount technology package.

The SKY67215-11 (400 – 700 MHz), SKY67216-11 (500 – 1200 MHz), SKY67221-11 (1600 – 2100 MHz) and SKY67226-11 (2100 – 3000 MHz) are designed for next generation wireless infrastructure applications including femto and pico cell access points micro base stations, tower mounted amplifiers, remote radio units and in-building repeaters/cell signal boosters. These fully integrated LNAs are fully matched to 50 Ohms and require only a single, external component. The internal biasing and matching network saves additional components and board space. The LNAs are available in a compact, 4 x 4 mm multi-chip module based restriction of hazardous substances compliant, surface mount technology package.

Both new enhancement mode GaAs pHEMT based LNA families offer low noise figure of <1.0 db.

Pricing and Availability: Skyworks’ new LNAs are currently available for both sampling and production use.
