The Mini-Circuits ZCDC20-5R263-S+ wideband directional coupler offers exceptional performance
operating over 0.5 to 26.5 GHz. This coupler has excellent coupling flatness, good directivity, and power
handling. It is ideal for lab testing applications as well as for power monitoring over wide bands, among
other applications.
Key Features
Feature
Wide bandwidth
Advantages
With a bandwidth spanning 0.5 to 26.5 GHz, ZCDC20-5R263-S+ coupler is ideal for
most lab testing applications, avoiding the need to switch components for different
frequency bands.
High directivity allows sampling of input powers with minimal detrimental effects due to
output mismatches.
Excellent Directivity
• 16 dB typ. up to 26.5 GHz
Excellent coupling flatness, ±0.8 dB typ
Excellent coupling flatness over the entire frequency range minimizes the need for
compensation circuits in most cases.
Good Return Loss (In & Out)
• 22 dB typ. up to 26.5 GHz
Good return loss over 0.5 to 26.5 GHz minimizes undesired reflections and resulting
amplitude ripple.
