Flexible TriQuint Broadband LNAs Simplify RF Design

The firm’s new low noise amplifiers provide flexible, highly-efficient linear solutions for mobile network base stations, repeaters, point-to-point radios, test and other high-performance applications.

Global RF solutions supplier and technology innovator, TriQuint Semiconductor has released 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 is focused on bringing performance innovation to essential building blocks in the global network.  This network is fraught with demand that continues to grow; according to 2011 Cisco Visual Networking Index, 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.

“Consumer demand for smartphones and tablets means more bandwidth through the network, which leads to the need for greater RF chain linearity", said Vice President Brian P. Balut. Our customers want to integrate functions for simplified design and greater efficiency. TriQuint solutions deliver by leveraging our unique technology portfolio and experience meeting worldwide network RF design requirements."

TriQuint’s new low noise amplifiers 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, these cascadable 50 Ω low noise amplifiers consume as little as 50 mA of electrical current and offer a variety of gain options from 15-19 dB; all operate on a single positive power supply (3V to 5V) and are unconditionally stable. TriQuint innovation includes these new products:

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

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

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

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

 Samples and evaluation boards are available and further details are available on TriQuint’s website.
