General Description
Pin Configuration
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 0.42
dB noise figure while drawing 70 mA current from a +5ꢀV
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 500ꢀ–ꢀ2000 MHz frequency
band and is targeted for wireless infrastructure. The
TQL9042 is packaged in a 3ꢀxꢀ3ꢀmm and is pin
compatible with the 1.5ꢀ–ꢀ2.7 GHz TQL9043 and 1.5ꢀ–ꢀ2.7
GHz TQL9044.
