Hi
The purpose is to apply DAC(AD9785) differential output signals to the I/Q mixer (HMC1056LP1BE), and in this design, balun should be used to convert the differential signal to single-ended and then apply to the mixer (HMC1056LP1BE).
1)We want use hmc1056 in direct conversion mode, should we use External 90-degree hybrid for IF1(I) / IF2(Q)?
1-1) If no, please confirm this operation without External 90-degree hybrid.
1-2) If yes, please suggest the SMD External 90-degree hybrid.
best regard
