The TQL9043 is a high-linearity, ultra-low noise gain block amplifier with a bypass mode functionality integrated in the product. At 1.9 GHz, the amplifier typically provides 18 dB gain, +35 dBm OIP3, and 0.5 dB noise figure while drawing 70 mA current from a 5 V supply. The component also provides high linearity in the bypass mode with 41.5 dBm IIP3.
The TQL9043 is internally matched using a high performance E-pHEMT process and only requires four external components for operation from a single positive supply: an external RF choke and blocking/bypass capacitors. This low noise amplifier contains an internal active bias circuit to maintain high performance over temperature.
The TQL9043 covers the 1.5-2.7 GHz frequency band and is targeted for wireless infrastructure. The TQL9043 is packaged in a 3x3mm and is pin compatible with the 0.5-2.0 GHz TQL9042 and 2.3-2.7 GHz TQL9044.
