TriQuint High Linearity LNA
Gain Block Amplifiers
TriQuint Semiconductor High Linearity LNA Gain Block Amplifiers are cascadable, high linearity gain block amplifiers in low-cost surface-mount packages. TriQuint Semiconductor High Linearity LNA Gain Block Amplifiers have the benefit of having high gain across a broad range of frequencies while also providing very low noise. This allows them to be used in both receiver and transmitter chains for high performance systems. The amplifiers are internally matched using a high performance E-pHEMT process and only require an external RF choke and blocking/bypass capacitors for operation from a single +5V supply. The internal active bias circuit also enables stable operation over bias and temperature variations. At 1.9 GHz, the amplifiers typically provide 22 dB gain, +39.5 dBm OIP3, and 1.3 dB Noise Figure while only drawing 115 mA current. They are housed in leadfree/green/RoHS-compliant industry-standard 16-pin 3x3mm QFN packages. The amplifers cover the 0.05 - 4GHz frequency band and are targeted for wireless infrastructure or other applications requiring high linearity and/or low noise figure.
