Hi, there

 

I choose AD8375 because of It's IMP data only ( i.e., 2nd harmonic ). 

In evaluation board schematic I need some clarification,

 

Below things are I observed from the  evaluation schematic ,

 

  1. 1. There is no intersection loss in the input matching circuit.
  2. 2. But the output matching network has 11 dB insertion loss because of the resistors,

 

Now my Question " Is it possible to use the output matching network a like in the input ?"

 

Please check the resistors values in the input & output matching networks.

 

Clarify my doubts

 

Thanks!

 

Br,

Wayne
