PPM Calculations
The electrical Phase length of any coaxial cable will change over temperture. To calculate the expected phase change of a Dynawave cable for any given temperature range use the following method.
Calculate the phase change of a 36 inch long DF118 assembly at -30 C at 12 GHz.
Determine the absolute phase (?) of the assembly at 25 C.
From the DF100 series ppm charts -30 C produces 1300 ppm of phase change.
