摘要：

A broadband, DC to 40 GHz 5-bit MMIC digital attenuator has been developed. The attenuator has been fabricated with 0.15 mu m GaAs pHEMT process. This attenuator has 1 dB resolution and 23 dB dynamic range. High attenuation accuracy has been achieved over all attenuation range and full 40 GHz bandwidth with the reference state insertion loss of less than 6 dB at 20 GHz. The input and output return losses of the attenuator are better than 14 dB over all attenuation states and frequencies.
