I am very new in electronic circuits and I am using NE612 as a frequency
mixer. In the datasheet a sample circuit for this purpose is shown.
Nevertheless, it is for 45 MHz. There are some capacitors and inducers
shown in the circuit diagram. However, I need to use some other
frequencies as well. I was wondering if the values of capacitance and
inductance which are shown in the datasheet should be changed for
frequencies other than 45 MHz. I am not using it in radio applications,
so I only need to have the IF produced in the output. I am really
looking forward to hearing some help. If I have to change them, how
should I measure them?
Thanks a lot for all helps

I suggest you refer to the application notes for the device. This will probably be your best source of information.

Resonance is when X [sub] L = X [sub] C

The Smith Chart leaps to mind as well.
