Note
Note that the Baluns on the Rev C board (T101-T104) are either:
Johanson Technology’s 2450BL15B050E 2.45 GHz Balun. This balun is rated for a operating frequency of 2400~2500 MHz and is connected to RXB Input and TXB Output. If you want to evaluate the part outside of this frequency range, use the other SMA.
Mini Circuits TCM1-63AX+. They are rated for an operating frequency between 70 MHz and 6 GHz, and are connected to the RXA Input and TXB Output.

I/O Voltage
The AD-FMCOMMS4-EBZ (AD9364) assumes a VDD_INTERFACE voltage between 1.71V and 2.625V (1.8 to 2.5 +/- 5%), so on your FPGA carrier board, you should ensure that VADJ is between these levels. Setting things to 3.3V will damage the part.
