I will use 3 way power splitter and power detector. 1. This is power splitter data sheet. In this data sheet, there are different isolation values. What does it mean?? Also in that point, I wonder definition of isolation at power splitter. 2. This is power detector data sheet. In this data sheet, Each pulse response rise/fall time are 400/10 or 800/400. What is difference between 400/10 and 800/400? What does it mean?
