4. The design is simple and compact, easy to carry and easy to install.
5. DC current pass through input to output.
6. Applications: lab use, VHF and UHF, Defense.
7. Model Number: KDC-4/40-3S
8. It is a Directional Coupler with Frequency 4 to 40 GHz, Coupling 20±1dB, Amplitude Banlance 1dB, Phase Banlance 8°, Average Power 10 W. Module with 2.92-Female Connectors.and is ideal for electronic warfare (EW), commercial wireless, SATCOM, radar, signal monitoring, and measurement, antenna beamforming, and EMC testing environments. It is available in a module with 2.92-Female connectors and is ideal for applications where precise monitoring, external leveling, signal mixing or swept transmission and reflection measurements are desired. Coupled ports are DC isolated and will only pass RF.
Key Features
Feature |
Advantages |
Wide bandwidth |
With a bandwidth spanning 4000 to 40000MHZ,Directional coupler is ideal for most lab testing applications, avoiding the need to switch components for different frequency bands. |
RF input power handling up to 10W |
Usable in systems with medium power requirements. |
Excellent coupling flatness, 20±1 dB typ | Excellent coupling flatness over the entire frequency range minimizes the need for compensation circuits in most cases. |
VSWR 1.6: 1 typ. |
Good VSWR over 4000 to 40000MHZ minimizes undesired reflections and resulting amplitude ripple. |
