Phase distortions can occur from frequency dispersion in waveguides and from other components in the system. If your system has this issue, Exceed Microwave's phase equalizer can reduce the cubic and parabolic phase distortion which will help linearize the phase.

As an example, we have produced phase equalizers that reduced 150deg p-p of parabolic phase distortion down to 15 deg p-p.

Exceed Microwave also supplies waveguide amplitude slope equalizers which will help flatten out the system passband slope.
