Key Features



Wide bandwidth

With a bandwidth spanning 500 to 18000MHZ, Directional coupler is ideal for most lab testing applications, avoiding the need to switch components for different frequency bands.

Excellent Directivity

• 15 dB typ

High directivity allows sampling of input powers with minimal detrimental effects due to output mismatches.
Excellent coupling flatness, ±20 dB typ Excellent coupling flatness over the entire frequency range minimizes the need for compensation circuits in most cases.

VSWR 1.5: 1 typ.

Good VSWR over 500 to 18000MHZ minimizes undesired reflections and resulting amplitude ripple.
