WebSilicon Labs WebBoth the RF and IMAGE frequency will be translated to the same IF frequency. With a 10.7 MHz IF frequency, the image is always outside of the FM broadcast band. Therefore, strong in-band FM signals are never to be found at the image frequency. A preselection filter can be used to reject this image that is 21.4 MHz away from the desired RF signal.
