I have a question about connection of AD9152 and ADL5375. Can AD9152 be connected to ADL5375 without DC cut capacitor? If yes, could you please advise me the circuit of that?
There are two versions of ADRF6720. One is ADRF6720 that asks 0.5V common mode voltage and the other one is ADRF6720-27 for 2.7V common mode voltage. So ADRF6720-27 matches to AD9152. Please refer to below figure 45 for two combinations of DAC and Modulator. You can refer to ADRF6720 and ADRF6720-27 datasheet. ADRF6720/ADRF6720-27 is PLL/VCO integrated Modulator supporting upto about 3GHz. You can interface AD9152 to either ADL5373-05/15 with some additional circuit like a level shifter. I copy examples at ac coupling case.
