The D-ATT20B is a 20dB, 50Ω Fixed Attenuator with BNC Male to BNC Female connectors. With its Brass Nickel Body, it is Rated to 2 Watts up to 3GHz. RF microwave attenuators, also known as RF pads, lower the amplitude of the signal with a known amount and can be used in a wide range of applications. The attenuator pads can be used when a signal needs to be reduced to protect measurement equipment or other circuitry, to extend the range of power meters and to impedance match circuits by reducing the VSWR seen by adjacent components. RF attenuators can prevent signal overload in receivers and detectors, adjusting the signal level to a range that is optimal.
