  • High frequency attenuator
    Patent number: 3984793
    Abstract: A continuously variable high frequency resistance attenuator is described in which the attenuation is first order independent of frequency. The wave translating media into and out of the attenuator provide a constant characteristic impedance. The attenuator consists of a length of series resistance and a plurality of parallel shunt resistors, which are of adjustable value and extend between the length of series resistance and ground or extend between the length of series resistance and open circuit.
