The TQP3M9040 is a high linearity, ultra low noise figure dual device amplifier in a 4x4 mm package. At 1.95 GHz in a balanced configuration, the LNA provides 18 dB gain, 22 dBm IIP3 and 0.67 dB noise figure. The part does not require a negative supply for operation and is bias adjustable for both drain current and voltage. The device is housed in a green/RoHS-compliant industry standard QFN package.

The TQP3M9040 consists of a single monolithic GaAs E-pHEMT die and  integrates bias circuitry as well as shut-down capability allowing the LNA to be useful for both FDD and TDD applications.  The TQP3M9040 is optimized for the 1.5 - 2.3 GHz band, but can be used outside of the band. TriQuint offers pin-compatible dual LNAs for the 0.5 - 1.5 GHz band (TQP3M9039) and 2.3 - 4.0 GHz (TQP3M9041). The balanced amplifier is optimized for high performance receivers in wireless infrastructure and can be used for base-station transceivers or tower mounted amplifiers.
