• Product Model:
    Filtered Dual Amplifier (LNFDA)



    The LNFDA is a broadband dual amplifier that is characterized to a specific customer specified frequency within the operating band and includes two integrated lowpass filters. The LNFDA’s integral 5-section LPFs attenuate unwanted harmonics and other undesired signals before and after amplification. A wide selection of common amplifiers and input/output attenuators provide flexibility in configuring gain and input/output levels (see amplifier selection table for options). Residual phase noise is verified at 100 MHz unless otherwise specified. Please consult our technical staff for assistance in configuring an amplifier to suit your input and output requirements.
