Abstract
The disclosure provides circuitry and methods to determine the reflection coefficient of a transmission line connected another physical element or device such as an antenna. The outgoing and the reflected signals on the transmission line are compared using two separate paths, with one path going through a signal conditioning circuitry such as an equalizer. The two paths are then combined and detected. A lookup table may be used for non-linear responses.
