I have a sinusoid signal that is modulated to 915 MHz. I would like to downcovert the signal through a series of intermediate frequencies (IF) and ultimately to the baseband. If I downconvert the signal to a 50 MHz carrier signal, and then pass the signal through a mixer with a 50 MHz local oscillator (LO), I receive the following error in Simulink:
Error using ==> rfckt.mixer.convertfreq Mixer output frequency is negative. Check FLO of MIXER and the simulation frequency.
