I recently bought 2 evaluation boards for the RF-synthesizer ADF4350, which is the EVAL-ADF4350EB1Z.
I designed my own evaluation boards using the MSP430 and CP2101 for communication with the computer.
As a comparison and for simplicity, I decided to use FR4! Losses are huge!
I would like to know what material is used by Analog Devices for the EVAL-ADF4350EB1Z.
