Product Overview
The Mini-Circuits ZUDC familꢂ of ultra-wideband directional couplers offers exceptional performance
spanning frequencies from 0.5 to 18 GHz. Available in models with 10, 20, and 30 dꢁ coupling, these
couplers provide excellent coupling flatness, good directivitꢂ, and power handling up to 50W. Theꢂ
are ideal for lab testing applications as well as for power monitoring over wide bands, among other
applications.
Key Features
Feature
Advantages
With a bandwidth spanning 0.5 to 18 GHz, ZUDC couplers are ideal for most lab test-
ing applications, avoiding the need to switch components for different frequencꢂ bands.
Ultra-wide bandwidth
Excellent Directivitꢂ
• 22 dꢁ at ꢀ GHz
• 12 dꢁ at 18 GHz
High directivitꢂ allows sampling of input powers with minimal detrimental effects due to
output mismatches.
Excellent coupling flatness over the entire frequencꢂ range eliminates the need for com-
pensation circuits in most cases.
Excellent coupling flatness, +0.ꢀ dꢁ tꢂp.
Good Return Loss, 15 dꢁ tꢂp.
Good return loss over 0.5 to 18 GHz minimizes undesired reflections and resulting am-
plitude ripple.
