applications.
Key Features
Feature
Advantages
With a bandwidth spanning 18 to 26.5 GHz, ZCDC20-18263-S+ coupler is ideal for
most lab testing applications, avoiding the need to switch components for different
frequency bands.
Wide bandwidth
Excellent Directivity
• 21 dB typ. up to 26.5 GHz
High directivity allows sampling of input powers with minimal detrimental effects due to
output mismatches.
Excellent coupling flatness over the entire frequency range minimizes the need for
compensation circuits in most cases.
Excellent coupling flatness, 0.2 dB typ
Good Return Loss (In & Out)
• 18 dB typ. up to 26.5 GHz
Good return loss over 18 to 26.5 GHz minimizes undesired reflections and resulting
amplitude ripple.
