Broadband BTS LNAs are deliver flexibility and simplify RF design requirements

June 29, 2011 // Jean-Pierre Joosting

TriQuint Semiconductor has released four 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; 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.

TriQuint's latest 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 Ohm 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 (3 V to 5 V) and are unconditionally stable.

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; and electrical current consumption (Idd) is 50 mA.

The TQP3M9006 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; and 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; and electrical current consumption (Idd) is 125 mA.

The TQP3M9028 has a low 2.0 dB noise figure and 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; and electrical current consumption (Idd) is 85 mA.
