INTRODUCTION OF 5G Diplexer & Duplexer
Both Diplexer and Duplexer can be taken as "Duplexers", "5G Duplexers", "5G Diplexers" or "VHF UHF Duplexers" which are extremely common radio frequency components in transmitter circuits, receiver circuits, and transceiver circuits used in communications, Radar, and other sensing applications under VHF UHF Band. Both VHF UHF Diplexer and VHF UHF Duplexer are three-port RF components, which use the frequency division function of high-pass, low-pass, or band-pass to run two signals of receiving and sending simultaneously under the same antenna or transmission line function.
Simply, the function of VHF UHF Diplexer & Duplexer is used to process 2 signal frequency bands which are from VHF to UHF at the same time, mainly based on the frequency band that the terminal device wants to operate. Except for 2 specific frequency bands, the other parts are treated as noise, which is isolated and removed. Usually, VHF UHF Diplexer & Duplexer is directly connected to the antenna terminal, and the signal collected by the antenna terminal is processed, and then respectively guided to the corresponding equipment.
Diplexer & Duplexer play a vital role in RF systems. It is a key element in wireless communication systems, enabling devices to transmit and receive simultaneously without the need for additional components or equipment. This makes communication equipment more compact and efficient. At the same time, Diplexer & Duplexer can also effectively isolate transmitting and receiving signals to prevent interference with each other, thereby ensuring the stability and reliability of communication, especially in dense wireless environments. In addition, Duplexer maximizes spectrum utilization, allowing transmit and receive operations on the same frequency, thereby increasing system efficiency and performance. All in all, the existence of Duplexer is crucial to achieve efficient and reliable wireless communication.
Diplexer & Duplexer in RF systems brings three major advantages.
- Simplifying the system architecture
It greatly simplifies the system architecture. Diplexer & Duplexer allow transmitting and receiving on the same frequency, so no additional equipment and components are required to achieve two-way communication. This means that when designing and implementing the system, the structure of the entire system can be more simplified and streamlined, thus saving time and resources.
- Improving efficiency
Diplexer & Duplexer improve the efficiency of the system. It effectively isolates the transmitting and receiving signals to prevent interference with each other and ensure the stability and reliability of communication. This means the system can work more efficiently, improving the overall performance and efficiency of the system.
- Reducing costs.
Diplexer & Duplexer can reduce system costs. Since it enables two-way communication on the same frequency, no additional spectrum resources are required, thus saving costs. At the same time, the equipment and components required for the system are reduced, further reducing the overall cost of the system.
Above all, Diplexer & Duplexer, as an important component in the RF system, not only simplifies the system architecture, improves efficiency, but also effectively reduces costs, making it one of the indispensable tools for many RF engineers.
Diplexer & Duplexer play important roles in different application scenarios.
- A. Mobile communication:
In mobile phone communications, Diplexer & Duplexer play a key role, allowing mobile phones to transmit and receive signals at the same time. This means that users can receive signals from other users while making voice calls or data transmissions. The function of Diplexer & Duplexer is to isolate the transmitting and receiving parts to ensure that the signals will not interfere with each other and realize the two-way communication function.
- B. Satellite communications:
In satellite communications, Diplexer & Duplexer are also indispensable components. Satellite ground stations need to communicate with multiple satellites to achieve communication functions within the coverage area. Duplexer ensures that the ground station can transmit and receive signals at the same time, allowing the ground station to effectively communicate with multiple satellites, thereby achieving wide communication coverage.
- C. 5G base station:
In 5G base stations, the application of Diplexer & Duplexer is more complex, but equally important. 5G technology requires high-frequency and high-speed data transmission, thus requiring more complex communication systems. Diplexer & Duplexer ensure that the base station can serve multiple users at the same time and achieve high-speed data transmission and low-latency communication. It helps base stations switch between different frequency bands to ensure that users can receive high-quality communication services. These functions of Duplexer make it a key component of 5G base stations and promote the development of 5G technology.
In general, Diplexer & Duplexer have an important position in the application of mobile phone communications, satellite communications, and 5G base stations, providing strong support for the development of wireless communication systems.
The key difference between VHF UHF Diplexer and VHF UHF Duplexer is the way the loop operates. VHF UHF Duplexer is based on two Bandpass filters, which protect the frequency bands that the terminal equipment will operate separately. In addition to better isolation between the two operating frequency bands, it can also fully isolate the noise outside the two frequency bands. The disadvantage is that it requires high technical skills and it is difficult to meet all development requirements.
On the other side, VHF UHF Diplexer uses 1 lowpass filter and 1 highpass filter to achieve the purpose of protecting 2 operating frequency bands. The advantage is that it is easier to meet various design needs, eg: 2 frequency bands are requested to be very close, working frequency band needs to have a large Bandwidth, but the disadvantage is that it is easily interfered with by additional noise because both lowpass filter and highpass filter can only provide unilateral noise isolation performance, and noise can easily break through the protection and enter these 2 operating frequency bands.
1. The function of RF Diplexer
Diplexer is a communications device often used in combination with RF filters to separate signals of different frequencies on a single antenna. It allows two different devices to share a communication channel so that they can transmit and receive information at the same time without interfering with each other. Diplexer consists of two filters (such as low-pass, high-pass or band-pass) that separate signals in different frequency ranges, thereby ensuring frequency separation between communication devices.
2. The function of RF Duplexer
Duplexer is a key component in wireless communication systems, used to separate the transmitting and receiving paths so that same-frequency signals can communicate bidirectionally on the same channel. It is not only suitable for signals of the same frequency, but also effectively handles signal flows in different directions. In Duplexer, there is no direct path between the transmitter and the receiver, but through a circulator-like mechanism, that is, the signal from port 1 is routed to port 2, and the signal from port 2 is routed to port 2. Port 1 and Port 3 are isolated from each other. This design ensures isolation between signals while achieving two-way communication requirements.
