Hi,

You could use a "Complex to Float" to separate the I and Q components, followed by a "Float to Complex", inverting the re and im inputs.

Thank you for responding, but what I meant by invert is swapping the I and Q components of the signal.

Complex conjugate only inverts the imaginary (Q) part of the signal.
If you want to invert both, just multiply with -1.
