    I have measured the output power from the RF8 port on an ADF4371 evaluation board.  I'm planning on using an ADF4372 on a new design.  In terms of output power, can I assume the performance on the RF8 port is the same between these two parts?

      Hi,
      

      RF8 output port of ADF4372 and ADF4371 provides same performance. You can safely change ADF4371 with ADF4372. 
      

       I don't have s-parameter measurement that I can provide. Most of the specs given in the datasheet is taken with a balun at the output (Marki BAL-0036). You can use pull-up inductors at the outputs and use AC coupling capacitors and combine outputs after AC coupling with a balun. I don't see any problem with that. 
      

      Regards,
      

      Kudret
