8.2 Termination

In high frequency applications, reflections occur if signals are not properly terminated. Figure 60 shows a

properly terminated signal while Figure 61 shows an improperly terminated signal.

Figure 60. Properly Terminated Signal

Figure 61. Improperly Terminated Signal

To minimize reflection, coaxial cable with matching characteristic impedance to the signal source should be

used. The other end of the cable should be terminated with the same value terminator or resistor. For the

commonly used cables, RG59 has 75

Ω characteristic impedance, and RG58 has 50Ω characteristic impedance.
