I have a question to ask for some advices. The appendix show the Schematic of ADL5380 and hmc960 . The output of IQ magnitude is imbalance. The magnitude of I channel is twice than that of Q channel at some frequence.
And it doesn't reach the target in datasheet. Is my schematic is not right at somewhere? I have no idea about it. My test frequence is 2G to 6G in RF and LO .Then, output is IQ sine wave whose frequence is 10KHz ~ 20KHz.
Look forward to your reply !!
