Hello,
Can you please provide S parameter data for the LO input and RF output ports for the ADL5371?
Thanks.

Q.
Could you please tell me how we test the P1dB of an IQ Modulator like the ADL5375 or ADL5370/1/2/3/4? Since the P1dB is so high, how do you apply a baseband signal of such a high high level?

Q.
What is the Thermal Resistance of LFCSP packages used in ADL5370/1/2/3/4/5 Modulators?

Q.
I want to use the Auxiliary DACs of the AD9779A to compensate away the LO Leakage of an IQ Modulator. I am using the recommended schematic from the data sheet of the ADL5370/1/2/3/4 family of IQ Modulators. What resistor tolerance should I choose for…

It is good to hear that the output power of ADL5385 is now normal. In terms of EVM, please check LO Leakge level which is also related to EVM performance. If possible, you can get better EVM by nulling LO Leakage level. Refer attached file for correcting…
Hi Matthias,
Thanks for your answer, it was very detailed and most helpful. I'd come to the same conclusiion that I and Q outputs are fixed at 90-deg and no trimming is possible although I was hoping I'd missed something in the DDS datasheet. It does…
