  An active microwave C-section is proposed which provides a flat magnitude
transmission in a wide frequency band along with a frequency-dependent group
delay response considering practical dissipation losses. The key lies in
integrating a constant gain amplifier inside a microwave C-section, which
perfectly compensates the distributed conductor and dielectric losses of the
coupler, while preserving the intrinsic dispersion of the C-section. The
operation of the proposed device is confirmed using numerical analysis.
