We are looking for a pair of IQ modulator and de-modulator, which can be used as a loop back potential.
Looking at one of old threads below, it covers some of our questions.
We'd like to use evm boards, of IQ demod adrf6820 or adrf6821 and IQ mod adrf6720 or adrf6720-27, together with DAQ2.
Our aim is to generate 500Mhz bandwidth RF signal while carrier frequency is not so important for now.
our question is that, is it possible to build a loop back mode use these IQ mod and demod evm boards?
