General Description
The TQL9043 is an ultra low noise, high-linearity gain
block amplifier with an integrated bypass mode function.
At 1900 MHz, this amplifier typically provides 17.5 dB
gain, +33 dBm OIP3 and 0.6 dB noise figure while
drawing 80 mA current from a +5 V supply. The
TQL9043 also provides high linearity in the bypass mode
with +41 dBm input IP3.
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.
