Intermodulation

Intermodulation occurs when multiple radio signals, transmitted simultaneously, mix together in a non-linear device or component, creating new signals at frequencies that are sums and differences of the original ones. Think of it like musical notes combining to produce new, unintended tones. In radio systems, these unwanted signals can cause interference, noise, and reduce the clarity of communication. It’s a common issue in electronic devices where signals interact within components that don’t respond linearly, highlighting the importance of proper design and filtering to prevent these unwanted effects.
