Anatech Electronics has introduced the Model AB2436B480, a ruggedized, weatherproof cavity bandpass filter for outdoor IEEE-802.11b/g WiFi installations that has excellent harmonic rejection, handles up to 50 W of RF input power, and is extremely selective.

As one of the fundamental signal processing components in RF and microwave circuits, the filter plays a critical role in determining any system’s ultimate performance. Since the electromagnetic spectrum has become more and more densely populated, filter performance has taken on greater significance than ever because interference rejection is of paramount importance.
