A Quad-Band Combiner is a specialized RF (Radio Frequency) device designed to combine or distribute signals across four different frequency bands into a single transmission line or antenna system. It optimizes signal efficiency while minimizing interference, making it essential in multi-band wireless communication systems.
The Quad-Band Combiner employs passive filtering technology (e.g., cavity filters or duplexers) to isolate and merge signals from the four bands. Each input port is tuned to a specific frequency range, while the combined output maintains low insertion loss and high isolation between bands. This prevents cross-interference and ensures signal integrity.
In a cellular tower, a quad-band combiner allows a single antenna to transmit/receive GSM (900MHz), LTE (1800MHz), and 5G (3.5GHz) signals simultaneously.
