Product Overview

1. 10db 50ohm Directional Coupler SMA-Female connectors full-band 1GHZ-18GHZ. The 10db Directional Coupler can continuously sample the transmission power along a certain direction of the transmission line, and can divide an input signal into two signals with equal amplitude and 90°phase difference.

2. Port Connectors: SMA-female connector.

3. The design is simple and compact, easy to carry and easy to install.

4. DC current pass through input to output

5. Applications: lab use,VHF and UHF, Defense

6. Model Number: KDC-1/18-10S

7. Directional Coupler that operates from 1to 18 GHz and support development of C-Band Radar Sub-Systems. It has an insertion loss of 1.0 dB and a directivity of 12 dB. The coupler Power Handling up to 10 W. It has a coupling variation of ± 1.5 dB and a VSWR of less than 1.5:1. This RoHS compliant coupler is available in a module that measures 70 x15 x 11 mm and can accurately determine signal to noise and transmit power when used in a radar.

Key Features



Wide bandwidth

With a bandwidth spanning 1000 to 18000MHZ, Directional coupler is ideal for most lab testing applications, avoiding the need to switch components for different frequency bands.

Excellent Directivity

• 12 dB typ

High directivity allows sampling of input powers with minimal detrimental effects due to output mismatches.
Excellent coupling flatness, ±1.5 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 1000 to 18000MHZ minimizes undesired reflections and resulting amplitude ripple.
