In a low-IF receiver, the radio frequency (RF) signal is mixed down to a non-zero low or moderate intermediate frequency (IF) in the range of a few hundred kilohertz. Typical frequency values are a few megahertz (instead of 33–40 MHz) for TV, and even lower frequencies, typically 120–130 kHz (instead of 10.7–10.8 MHz or 13.45 MHz) in the case of FM radio receivers or 455–470 kHz for AM radio (MW/LW/SW) receivers.
