    DESCRIPTION

    The LNAA is a low noise, low frequency amplifier with a customer-specified fixed gain between 30 and 60 dB. This amplifier module is designed to serve as a preamplifier for phase noise measurement systems where very low flicker and white noise is required and is equally useful in many applications where low noise is a critical parameter.

     

    FEATURES:

    • < 1 nV/root-Hz, Input Referred
    • Bandwidth 10 Hz to 1 MHz
    • Fixed Gain from 30 to 60 dB
    • 50 ohm or High-Z Input
    • Low Output Z

     

    APPLICATIONS:

    • Low Phase Noise Measurements
    • Audio Signal Amplification
