Part number TQL9042 Product Type Amplifier from Manufacturer Qorvo

Status: Discontinued | Data Sheet: pdf link image   | RoHS Compliance: Rohs Compliant

The TQL9042 is a high-linearity, ultra-low noise gain block amplifier with a bypass mode functionality integrated in the product. At 900 MHz, the amplifier typically provides 19 dB gain, +36 dBm OIP3, and 0.42dB noise figure while drawing 70 mA current from a 5V supply. The component also provides high linearity in the bypass mode with +43 dBm IIP3.

The TQL9042 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 to maintain high performance over temperature.

The TQL9042 covers the 500-2000 MHz frequency band and is targeted for wireless infrastructure. The TQL9042 is packaged in a 3x3mm and is pin compatible with the 1.5-2.7 GHz TQL9043 and 2.3-2.7 GHz TQL9044.
