simulink real to IQ

is there a simulink block that can convert real sine wave data to IQ data?

Simulink does not have an IQ datatype, so it is difficult to know what you are asking for.

Simulink has a real + imaginary to complex block https://www.mathworks.com/help/simulink/slref/realimagtocomplex.html but that forms complex numbers.

The MATLAB / Simulink internal representation of complex numbers currently interweaves real and complex data; this is relatively new, with it not being all that many releases ago when complex numbers were represented by an array of real values and a seperate array of imaginary components.

I guess you could use the real+imaginary to complex block with constant imaginary part of 0; the result would in some meaningful sense be IQ data
