• Product Model:
    Audio Amplifier (LNAA)



    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.
