I have a design on ltspice for a modulator and demodulator of radio frequency signals. The multiplier was not one of the models in ltspice so I downloaded it from the analog devices website.
The balanced modulator simulation worked perfectly. However when I added the demodulator circuit I get 'time step too small'. The demodulator still has the same transmission frequency as in the modulator so this can't be the cause of the error. So the problem must be in the output of the modulator.
I have attached the ltspice schematic. I have had a lot of problems with that error and would like to know how to fix it?
