• Product Model:
    Filter Amplifier (LNFA)



    The LNFA is a broadband amplifier that is characterized to a specific customer specified frequency within the operating band and includes an integrated bandpass filter. The LNFA’s integral 2-section BPF attenuates unwanted mixer products, harmonics and other undesired signals at the output before amplification. A 3 dB bandwidth, typically 5 – 10% of the center frequency, is standard.  A wide selection of common amplifiers and input/output attenuators provide flexibility in configuring gain and input/output signal levels (see amplifier selection table for options). Residual phase noise is verified at the design frequency when suitable low noise sources are available. Please consult our technical staff for assistance in configuring an amplifier to suit your input and output requirements.
