Performance Advantages and Design Techniques for THz Schottky Diode Limiters

Limiters are critical components in the front end of nearly every modern RF receiver. As system-level requirements of modern transceivers become more stringent, this drives a need for RF components that can offer near-ideal performance at every point along the chain. For a limiter, this means instantaneous recovery times, near-zero spike leakage, and thermal properties that allow for unaltered performance in high-power pulsed conditions. In this paper, we will discuss the massive performance advantages offered by THz Schottky diode-based limiters, how to optimize limiter designs, and how system-level requirements are simplified through the adoption of this limiter technology.
