Product Overview Mini-Circuits’ EDC21-24+ is a 21 dB directional coupler that operates from 4 to 20 GHz packaged in MCLP 4 x 4mm, 24-lead package. 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 relatively high repeatablility in performance.


• low mainline loss, 0.7 dB typ.
• excellent coupling flatness, ±2dB
• small size, 4×4 mm
• highly repeatable performance (GaAs based design)
• no external termination required.
