Mini-Circuits’ EDC10-273-DG+ is a 10 dB directional coupler die that operates from 6 to 26.5 GHz. It provides excellent coupling flatness over a broad bandwidth and good return loss. This coupler also provides a quadrature phase shift between the signal at the through port and coupler port. Manufacturing using GaAs Technology, this model results in relativerly high repeatablility in performance.
