Hi

 

I measuered output power in the EVAL board of ADF4350 ADF4350EB2Z. This eval board is configured for UMTS bant (2110MHz to @170MHz) as specified in the datasheed of ADF4350. Now as mentioned on the page number 27 of the dathasheet output power from the evalboard is expected to be 5dBm single ended. I have measured output power from 3.5dB to 4.5dB across the frequency range (2110MHz to 2170MHz). Is my measurement is correct?
