Duplexers:

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?

1. Duplexers allows sharing of the same antenna for both transmit and receive modes. This minimizes the wireless system’s size and cost.
2. Duplexers provide isolation which protects the receiver from high power transmitters. Branch duplexer cost is low.
3. A balanced duplexer’s power handling capability is higher than a branch duplexer’s. It also has a higher operating bandwidth.
