This tool calculates the maximum length of a short jumper cable used in Radio Frequency circuits.

Enter the highest frequency of operation and the tool will provide the maximum length of the jumper wire.

**Example Applications**

Use the square wave harmonics calc to find the highest frequency components. For instance a 125 MHz square wave has frequency components up to 1375 MHz. Plug that number into the calculator and the max jumper cable length is 22 mm.

Find the bandwidth of a signal from its rise time. Use this number in the calculator. For example a signal with rise time of 1 ns has a bandwidth of 350 MHz. At this frequency the jumper length is 86 mm.

In general a jumper wire should have a length = (1/10)*λ, where λ is the minimum wavelength associated with the highest frequency signal on the wire.
