How much reflected power is acceptable

WebMar 17, 2024 · The measurement of the amount of light that is reflected back toward the source is called Return loss, and its unit of expression is also in decibels (dBs). Furthermore, this measurement parameter is always a positive number, and a high return loss is a favorable measurement parameter, and it typically correlates to a low insertion loss.

WebA reflection coefficient is defined as the ratio of reflected wave to incident wave at a reference plane. This value varies from -1 (for a shorted load) to +1 (for an open load), and becomes 0 for matched impedance load. It is a complex number. This helps us because we can actually measure power.
