The amplifier provides 16 dB of gain, 2 dB noise figure and +3 dBm input IP3 while requiring only 9 mA from a +3V supply. Using a single control line, the LNA can be switched into a low loss 2.2 dB bypass mode reducing the current consumption to 20 μA. A low cost, leadless 3x3 mm QFN surface mount package (LP3) houses the amplifier. No external RF matching components are required.
