Product Overview

1. 3dB 50ohm Directional Coupler 2.92-Female connectors full-band 4000MHz-40000MHz.

2. The 3dB 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.

3. Port Connectors: 2.92-female connector.

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



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.
