40dB Directional Coupler

A 40dB Directional Coupler is a crucial item to have in your toolbox whether you're planning a project in the field or trying to improve your communications system. You can link to additional transmitters and receivers by using a coupler, which can also enhance performance and let you make better use of your signal. Another excellent technique to prevent interference is via a directional coupler.


VSWR 1.3

The voltage standing wave ratio, or VSWR, measures the relationship between the maximum and minimum voltages in a standing wave pattern along a transmission line structure. In dB, this ratio is written. For instance, a signal at 2.45 GHz with a wavelength of 12 centimeters would have a VSWR of 1.30.

Standing waves in microwaves are quite uncommon. Instead, as waves move, they come into contact with an interface of dielectric characteristics that change with distance. This may obstruct the signal or reflect some of it. As a result, the pattern's intensity is inversely related to the strength of the two waves.

A Directional Coupler is typically constructed from two connected transmission lines. This enables the waves to exit the coupler ports and continue to propagate. The reference impedance is typically 50 ohms. The Greek letter sigma is used to represent VSWR in certain older microwave textbooks.

Two ports are normal for directional couplers, it is called Dual Directional Coupler. The output port is one, and the input port is the other. These ports can be utilized in a BTS application to simultaneously monitor forward and reverse power.
