I need help modeling the following IF transformer; see data sheet: https://www.mouser.com/ds/2/449/XC-600131-205883.pdf
It is the model no. 42IF123-RC 25K in, 4K out, cap color green.
I notice it's resonating at around 8 MHz instead of 10.7 MHz. Can anyone offer any feedback and/or advice on my circuit model? Do I have the Inductance values correct based on the data sheet? Do I have to use a more complex spice directive?
I have attached my spice circuit for LTspice using a simplified spice directive for the transformer.
Thanks,
Joe
