The main difference between the two circuits lies in the fact that the attenuator reduces the power signal by a predetermined ratio while the power limiter tends clipping incident signal below a threshold power.
Waveguide limiters are protector structures. Waveguide limiters protect the receiver circuits from high power microwave signals. Commonly used for input protection of electronic components in front end protection for LNA's, power leveling (limiting), receiver protection, radar & EW system and high-frequency instruments.
