WHAT IS AN IMPEDANCE MATCHER?

WHAT IS IMPEDANCE MATCHING AND WHY IS IT NEEDED?

At high frequencies, in addition to values such as resistance and capacity of the line, we encounter a new concept. The impedance of the line.

If the length and wavelength of the cable we use are comparable to each other, the impedance value of the line we use has become important for us.

For example, the wavelength of a 3Khz audio signal is about 300 Km, but the wavelength of a 3 Mhz signal is only 300 meters. If the cable used is a few Km long, it is now a transmission medium for us.

If there is a change in the impedance of the cable along the line, some of the signal we send will be reflected back, just as some of the light entering our mirror is reflected back. The amount of this reflection depends on the impedance of both cables and the distance of the connection from the signal source. In some special cases, the entire transmitted power may even be reflected.

Therefore, if the impedances of the copper cables we use are different, impedance matching will significantly improve the signal quality.
