Understanding Phase Versus Temperature Behavior

Understanding complex microwave transmission concepts can be difficult. Understanding complex material properties can also be difficult. Understanding phenomena that combine both of these can be mind boggling. Phase stability versus temperature is one of these phenomena.

This application note will provide the reader with a basic grasp of the situation. Before we can discuss phase stability we need a basic understanding of phase length and phase delay. Phase length, also known as electrical length, is the number of wavelengths in the cable assembly at a given frequency.
