Diplexers:

We offer a wide variety of diplexers, including RF diplexers and VHF UHF diplexers.A diplexer is a passive device that implements frequency-domain multiplexing. Two ports are multiplexed onto a third port. The signals on ports L and H occupy disjoint frequency bands. Consequently, the signals on L and H can coexist on port S without interfering with each other.

What is a diplexer used for?

A diplexer allows two different devices to share a common communications channel. Typically, the channel is a long coaxial cable, and a diplexer is often used at both ends of the coaxial cable. The plan is feasible if the two devices operate on different frequencies. The plan is economical if the diplexers cost less than running a second cable.Diplexers are typically used with radio receivers or transmitters on different, widely separated, frequency bands. A single city radio tower might have a police department antenna on 460 MHz and a fire department antenna on 156 MHz. A diplexer at the top combines the two antenna signals to the single coaxial feedline, and a second identical diplexer inside the building separates the feedline signals to the two dispatch radios. Some diplexers support as many as four antennas or radios that work on different radio bands.

What is the difference between a diplexer and a splitter?

In appearance, a splitter and a diplexer are very much alike. They both have multiple connections on one end and one connection on the other. However, a diplexer has two signal inputs and one signal output. Conversely, a splitter has one signal input and two signal outputs.

What is the difference between a diplexer and a duplexer?

A diplexer is a passive device that implements frequency-domain multiplexing. A duplexer is a 3-port device that allows the transmitter and receiver to use a single antenna, while operating at the same/similar frequencies. Its operation is facilitated by allowing two-way communication over a single channel by isolating the receiver from the transmitter while transmitting a pulse, and isolating the transmitter from the receiver while receiving a pulse, allowing them to share the same antenna.
