Design and Implementation of a Small-Step Power Digital Attenuator
Lei Zhu · Journal of Microwaves · 2010
In this paper,principle and application circuit of a small-step wide range digital attenuator is presented.By combining the advantage of high speed microwave switch,precision fixed attenuator and monolithic digital control attenuator,we solve the conflict between small-step and wide attenuator range,and achieve a better result.
