LTC5584 data sheet states on page 20:
I-Channel and Q-Channel Outputs
The phase relationship between the I-channel output signal and the Q-channel output signal is fixed. When the LO input frequency is higher (or lower) than the RF input frequency, the Q-channel outputs (Q+, Q–) lead (or lag) the I-channel outputs (I+, I–) by 90°.
But my measurement with the LTC5584 Demo Board results in the exact opposite:
I am confused... can anyone clear this up for me?
