The function of AD8342-EVALZ-ND

Dear Sir/Madam,

I just bought the AD8342-EVALZ-ND and I read the data sheet of AD8342 which said that it could be used as both down-converter and up-converter. I want to make sure that if AD8342-EVALZ-ND can also be used as both a down-converter and an up-converter. If it could only work as a down-converter, is there any way I can change it to the up-converter since I need to use it as a part of TX-Transmitter?

Best Regards,
