Advantages of Antenna Diplexer

Cost and space savings

In large-scale 5G networks, antennas will need to be doubled due to shorter distances between base stations. By using an antenna duplexer, the number of antennas can be reduced by using the same antenna for both transmit and receive, thus reducing infrastructure costs.

Improve communication quality

Duplexers ensure that both transceivers and receivers operate simultaneously and smoothly by effectively isolating the transmit and receive signals. This design prevents the return of the local transmitter signal and ensures that the receiver is free from interference, thus improving communication quality.

Adaptable to a wide range of communication systems

Duplexer is applicable to a variety of wireless communication systems, such as GSM, CDMA and WCDMA, etc. These systems usually use filter-type antenna multiplexers, i.e. duplexers.

Stability and Durability

The structural robustness and stability of duplexers enable them to maintain stable communication quality in harsh environments. Their miniaturisation and ease of installation also make them suitable for mobile communications and unattended repeaters in the field.

Types of Antenna Diplexer
 
 

Same frequency duplexing

In this case, TX and RX operate in the same operating band at the same time, and the isolation of TX/RX is usually realised by the unidirectional transmission characteristic of a ferrite device such as a circulator. This type of antenna common is called a circulator type antenna common.

 
 
 

Dual frequency duplexing

In this case, TX and RX operate separately in the frequency band with a certain frequency division, and two filters are tuned in the corresponding frequency bands, and the antenna is shared in the form of a Y-junction. This type is called a common filter type antenna, in practice it is usually called a duplexer.

 
 
 

Same frequency half duplex

In this case, RX and TX operate in the same frequency band and the isolation between the two is realised by a switch, usually an SPDT switch. This category is called switched antenna common, usually referred to as transceiver antenna switch.

 
Application of Antenna Diplexer

 

Enabling multiple transmitters to use a single antenna

Broadcast stations often use multiple frequencies, possibly for different programmes / station names. In view of the size and cost of the antennas they may have a single vertical antenna and they may want to combine the signals from several transmitters to feed into the antenna. As they are on different frequencies, it is possible to use a diplexer to combine the signals and use a single feed.

 

Enabling a multiband transmitter to use different antennas according to frequency

Some transmitters like some ham radio transmitters can cover very wide ranges of bands - for ham radio transmitters there is a growing trend towards transmitters covering HF and VHF bands. They may even extend into the UHF region. Often one antenna system may be used for HF operation, and another for V/UHF operation. If there is a single transmitter output, a diplexer can be used to route HF signs to the HF antenna, and V/UHF signals to the V/UHF antenna.

 

Allowing single feeder to be used for multiple feeds, e.g. TV & radio

Within a domestic scenario, it is often useful to have an external VHF FM or digital radio antenna along with a television antenna using single feeder. The signals from he antennas can be combined at the antenna end using diplexer, and a second diplexer at the point of use to route the signals to the radio and television. This can work well because television signals typically use frequencies above 300 MHz, often 400MHz and more, whereas VHF FM radio is between 87.5 and 108MHz, of within the VHF band is digital radio is used.

FAQ

Q: What is the advantage of having diplexer?

A: 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.

Q: What does an antenna diplexer do?

A: A diplexer is a passive (RF) filter component with three ports, which enables the sharing of a common antenna between two distinct frequency bands. This technology allows transmitters operating on different frequencies to use the same antenna and each band may both transmit and/or receive.

Q: Where is diplexer used?

A: A diplexer is a device capable of either combining or separating signals at different frequencies. They are commonly employed throughout telecommunication and radio frequency engineering, typically when multiple signals of varying frequencies need to share a single atenna or cable.

Q: What service can you provide ?

A: We have customized service and after-sale service.We can produce according to your requirments.We will give your refund or replacement if there is quality problem about our products.

Q: What is the output of a diplexer?

A: A Diplexer is a 3 Port device: one Common and two Input/Output ports. One Input/Output port is the High Frequency connection while the other is the Low Frequency connection. Diplexers allow two different band radios to share a single antenna, or a single radio to use two different band antennas.

Q: What is an antenna diplexer?

A: An antenna diplexer is a device that allows multiple antennas to be connected to a single cable. It splits the signal into multiple outputs and prevents crosstalk between the antennas.

Q: What is an antenna diplexer used for?

A: An antenna diplexer is used to connect multiple antennas in a building or in a car. This is helpful in improving the signal and reducing space requirements at the same time.

Q: What are the different types of antenna diplexers?

A: There are different types of antenna diplexers such as frequency separation, polarization splitting, and time delay separation. Each type is designed for a specific application and offers different advantages.

Q: How can you guarantee your products quality ? And the warranty time ?

A: We have QC department who is responsible for each point quality from raw material to finished products.Our warranty time is 3 years.

Q: What is your MOQ ?

A: Our MOQ is 100 Pieces.

Q: What is your payment terms ?

A: 1)30%T/T in advance, 70%balance paid before delivery.

2)100% irrevocable LC at sight.

3)EXW price& cash price are also accepable.

4)Other payment terms can be negotiated between both sides.
