Where,

P1 = Input Power

P2 = Output Power at Port 2

P3 = Output Power at Isolated Port/Port 3

P4 = Coupled Power/Port 4

 

Example,

If P1 = 32 dBm, P2 = 29 dBm, P3 = 2 dBm and P4 = 7 dBm

Then, Coupling = 6.6005 dB, Coupling Loss = 1.0721 dB, Insertion Loss = -0.7463 and Directivity = 54404 dB
