Inherent isolation degrades as a function of Output Termination VSWR. As the Output Termination VSWR approaches 2.5:1, a combiner with infinite Inherent Isolation provides only 2 dB more Isolation than one with 15 dB Inherent Isolation, and only 1 dB more than a unit with 20 dB Inherent Isolation. Therefore, any investment in a unit … Read more

The primary difference between reactive power combiners and power combiners with isolation is what happens when signals are fed to the combiner inputs that are not perfectly matched in amplitude and/or phase.  In an isolated combiner, the amplitude and/or phase error is terminated in a resistive network whereas reactive combiners reflect non-coherent signals back to … Read more
