Reflection

coefficient = 0.6

Loss = 21.5 dB

Loss = 16.5 dB

Loss = 11.5 dB

5. Tic marks on x,y axes refer to reflection coefficient in increments of 0.1V. Reflection coefficients vary from -0.6 to +0.6 on both

the x and y axes.

6. Data is for vector modulators driven by linearizers. See Application Note AN3001.

7. Inputs to the linearizers vary from 0 to 5V.

8. The phase with the inputs to both linearizers set to +5V is arbitrarily called zero degrees.
