The TriQuint TQP3M9040 is a high linearity, ultra low noise figure dual device amplifier in a 4x4 mm package. At 1950 MHz in a balanced configuration, this LNA provides 18 dB gain, 21.8 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 1500−2300 MHz band, but can be used outside of the band. TriQuint offers pin-compatible dual LNAs for the 500−1500 MHz band (TQP3M9039) and 2.3−2.7 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.
