Product Description

Product Description

200W 20dB Directional Coupler(136-470MHz, N Female, IP60)

 

RF directional couplers are passive devices that couple power travelling through the device to another port enabling the signal to be used in another circuit. RF directional couplers can be implemented using a variety of techniques including stripline, coaxial feeder and lumped or discrete elements.


Directivity is a measure of how well the coupler isolates two opposite-travelling (forward and reverse) signals. In the case of measuring reflection coefficient (return loss) of a device under test, directivity is a crucial parameter in the uncertainty of the result.
