Our range of duplexer includes radio duplexers and UHF duplexers.
What is a duplexer?
A duplexer is an electronic device that allows bi-directional (duplex) communication over a single path. In radar and radio communications systems, it isolates the receiver from the transmitter while permitting them to share a common antenna. Most radio repeater systems include a duplexer. Duplexers can be based on frequency (often a waveguide filter), polarization (such as an orthomode transducer), or timing (as is typical in radar).What is the difference between a diplexer and a duplexer?
A duplexer separates a transmit and receive path based on signal direction and can be used for same frequency signals, and a diplexer separates signals based on frequency with filters. Their operation is not interchangeable, and a diplexer could not replace a duplexer in common circuits.What are the advantages of having a duplexer?
- Duplexers allows sharing of the same antenna for both transmit and receive modes. This minimizes the wireless system’s size and cost.
- Duplexers provide isolation which protects the receiver from high power transmitters. Branch duplexer cost is low.
- A balanced duplexer’s power handling capability is higher than a branch duplexer’s. It also has a higher operating bandwidth.
