TriQuint broadband LNAs eliminate matching components

TriQuint Semiconductor Inc of Hillsboro, OR, USA, which provides RF front-end product maker and foundry services to mobile device, networks, and defense & aerospace markets, has launched four new linear low-noise amplifiers (LNAs) that eliminate matching components in a wide range of high-performance broadband applications including 3G/4G base-station networks.

TriQuint comments that the global network is fraught with demand that continues to grow; by 2015, the amount of mobile data traffic contributed by tablets alone is expected to equal that of mobile data traffic from all devices combined in 2010 (according to the 2011 Cisco Visual Networking Index).

“Consumer demand for smartphones and tablets means more bandwidth through the network, which leads to the need for greater RF chain linearity,” says Brian P. Balut, TriQuint’s vice president Networks. “Our customers want to integrate functions for simplified design and greater efficiency,” he adds. “TriQuint solutions deliver by leveraging our unique technology portfolio and experience meeting worldwide network RF design requirements.”

TriQuint’s new LNAs are part of a wide-ranging portfolio created to provide flexible, highly efficient linear solutions for broadband markets including mobile network base-stations, repeaters, point-to-point radios, test and other high-performance applications. Available in cost-effective standard surface-mount packages, the cascadable 50 Ohm LNAs consume as little as 50mA of electrical current and offer gain options of 15–19dB; all operate on a single positive power supply (3–5V) and are unconditionally stable.

The new products include:

• TQP3M9005, which has a low 0.8dB noise figure and provides 15dB of gain at 1.9GHz; P1dB RF output is 22.3dBm; OIP3 is 34dBm; electrical current consumption (Idd) is 50mA.

• TQP3M9006, which has a low 1.0dB noise figure and delivers 13.5dB gain at 1.9GHz; P1dB RF output is 22.4dBm; OIP3 is 38.5dBm; electrical current consumption (Idd) is 90mA.

• TQP3M9007, which is a gain block that operates with a low 1.3dB noise figure while delivering 13dB gain at 1.9GHz; P1dB RF output is 23.6dBm; OIP3 is 41dBm; electrical current consumption (Idd) is 125mA.

• TQP3M9028, which has a low 2.0dB noise figure and provides flat gain (±0.2dB) across a wide bandwidth; it delivers 14.7dB gain at 1.9GHz. The device’s P1dB RF output power is 21dBm; OIP3 is 40dBm; electrical current consumption (Idd) is 85mA.

Samples and evaluation boards are available.
