In our situation, carrier wave form frequency is 60Mhz, we use AD9142A and AD9957 to perform complex digital modulation  and digital to analog conversion 。And we found if we use AD9142A ,we must use ADL5385 to match it.

if we use AD9957 , it do not need additional IQ modulator.

 

so for our situation ,which is better ?

 

And can we use fpga to perform IQ modulation , and use AD9122 to just perfom Digital to Analog conversion but IQ modulation ?

 

thanks !
