What is a Hybrid Coupler?
A hybrid coupler is a highly specialized RF passive component used extensively in telecommunications. Its primary function is to take an input radio frequency signal and split it equally between two output ports, introducing a strict 90-degree phase difference between those outputs. Conversely, it can be used to merge multiple signals together. Because of its internal design, it inherently provides high isolation between the input ports, preventing signals from bleeding into one another.
How a Hybrid Coupler as a Combiner Can Work
When utilized in a DAS network, a hybrid coupler is frequently deployed as a combiner to streamline infrastructure. Here is how it works:
Signal Input: Two separate wireless carriers (for example, an 800MHz LTE signal and a 3800MHz 5G signal) are fed into the two input ports of the coupler.
Phase Cancellation: Because the coupler applies a 90-degree phase shift, it mathematically isolates the input ports from each other.
Unified Output: The independent signals are safely combined and distributed equally to the output ports. This allows multiple base stations to share the same coaxial cable and antenna network without their high-power transmitters interfering with or damaging each other.
In the case of a 4×4 hybrid matrix, this combining capability is expanded. It uses a cascaded internal network of couplers to take four distinct carrier inputs and distribute them evenly across four identical outputs, making it the backbone of high-density neutral-host networks.
