Ultra Low Noise
    (Lower than the 50 Ω thermal noise of input
    resistance)
    Noise Figure:
    Less than 0.8 dB (15 MHz to 63 MHz)
    0.9 dB (83 MHz, at 50 Ω source)

Wideband: 300 k~ 100 MHz, +0.5, -3 dB

Fast Overload Recovery Time:
    Less than 200 μs (100 μs typ.)

High Gain. 44 dB ± 1 dB (15M~ 83MHz, at 50 Ω)
