Product Attributes

Introduction

The TQL9044 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 19.4 dB gain, +34.5 dBm OIP3, and 0.6 dB noise figure while drawing 70 mA current from a +5 V supply. The component also provides high linearity in the bypass mode with +36 dBm IIP3. The TQL9044 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 TQL9044 covers the 1.5 - 4.0 GHz frequency band and is targeted for wireless infrastructure. The TQL9044 is packaged in a 3×3 mm and is pin compatible with the 0.5 – 2.0 GHz TQL9042 and 1.5 – 2.7GHz TQL9043.
