Wideband Coaxial 10dB Directional Coupler




• High Directivity and  Minimal RF Insertion Loss

• Multiple, Flat Coupling Values available

• Microstrip, stripline, coax and waveguide structures are avaliable


Directional couplers are four-port circuits where one port is isolated from the input port.They are used for sampling a signal, sometimes both the incident and reflected waves 


Product Detail

Product Tags


Concept’s directional couplers can be used in applications for power monitoring and leveling, sampling of microwave signals, reflection measurements and for laboratory test and measurement, defense / military, antenna and other signal related uses.

10 dB directional coupler will provide an output of 10 dB below the input signal level, and a “Main Line” signal level which has very little loss (0.46 dB theoretically).


Availability: IN STOCK, NO MOQ and free for testing

1. Input power is rated for load VSWR better than 1.20:1.
2. Specifications are subject to change at any time without any notice.
3. The physical loss of the coupler from input to output in the specified frequency range. The total loss is the sum of the coupled loss and the insertion loss. (Insertion loss+0.45db coupled loss ).
4. Other configurations, such as different frequencies or different couplines , are available under different part numbers.

OEM and ODM servies are welcomed, 3dB, 6dB, 10dB, 15dB, 20db, 30dB, 40dB and 50dB customized couplers are avaliable. SMA, N-Type, F-Type, BNC, TNC, 2.4mm and 2.92mm connectors are avaliable for option.
