General Description
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 +5 V
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 3 x 3 mm and is pin
compatible with the 1.5 – 2.7 GHz TQL9043 and 1.5 – 2.7
GHz TQL9044.
