Duplexers

Duplexers play a crucial role in communication systems, especially in radio frequency (RF) and microwave applications. They make it possible to transmit and receive signals simultaneously over a single antenna. These devices keep transmit and receive signals separate, avoiding interference and allowing for the efficient use of one antenna for both tasks. Duplexers use filtering techniques to isolate transmitter and receiver frequencies, ensuring signals do not interfere with each other. Commonly, communication systems such as mobile networks, base stations, and two-way radio systems, where simultaneous transmission and reception are critical, rely on duplexers. By effectively managing signal paths, they enhance the overall performance and reliability of communication networks, minimizing signal loss and optimising signal quality.
