Desensitization of radio receivers is important where a number of radio signals are present in close proximity to each other in an area. This may happen in Wi-Fi to cellular communications to Bluetooth as well as in many more traditional applications. When a signal is being received in the presence of a strong interfering signal, then non-linearities within the receiver mixer and amplifier results in generation of spurious IF. If the interfering signal is sufficiently strong, the resulting product will suppress all other signals reducing the effective gain of the device.
