The results show that this attenuator, which is 12mm×8mm×0.5mm and works at low temperature, can be used alone or integrated into HTS system to decrease system volume and weight. Insertion loss of this attenuator is about 0.2dB, whose magnitude is one order lower than that of a conventional attenuator. Attenuation step about 0.01dB can be achieved, which is 1~2 orders lower in magnitude than conventional attenuators.
