Enter the coupling power and the input power into the Calculator. The calculator will evaluate the Coupling Loss. 

Coupling Loss Formula

CL = -10 * LOG ( 1- CP/IP)

Variables:

  • CL is the Coupling Loss ()
  • CP is the coupling power
  • IP is the input power

How to Calculate Coupling Loss?

The following steps outline how to calculate the Coupling Loss.

  1. First, determine the coupling power. 
  2. Next, determine the input power. 
  3. Next, gather the formula from above = CL = -10 * LOG ( 1- CP/IP).
  4. Finally, calculate the Coupling Loss.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

coupling power = 573

input power = 234
