AD-FMCOMMS2 BALUNs

Hello ADI, we are planning to use the AD-FMCOMMS2 board (which incorporates the transceiver AD9361).

Our purpose is to connect this board with a out door unit for microwave transmission width aprox. 6MHz signal bandwidth. That outdoor unit IF center frequency: 350 MHz for transmission and 140 MHz for reception.


Following http://wiki.analog.com/resources/eval/user-guides/ad-fmcomms2-ebz/hardware/configuration_options

I have to change the balun transformers in AD-FMCOMMS2 to operate in another frequency carrier.

 

I have the following questions:

 

- I am understanding that I will have to replace the 2450BL15B050E 2.45 GHz Balun on AD-FMCOMMS2 for TDK HHM1591D1 for transmission, is it correct?

- Which Balun I could use for reception?

- Could be better to use the AD-FMCOMMS3 board for this purpose? If yes, which will be the degradation?

 

Thank you for your answer
