Features:
- High Stopband Rejection
- Small Size
1. High Q value and low loss: The waveguide diplexer has a high Q value, which means its insertion loss is small and it can efficiently transmit microwave signals.
2. High isolation: The RF diplexer can achieve high isolation between transmission and reception, usually up to 55dB or even higher. This high isolation can effectively prevent the transmission signal from interfering with the reception signal, thereby ensuring the normal operation of the communication system.
3. High power capacity: Waveguide structures (such as rectangular or circular metal waveguides) are usually made of highly conductive metals (such as aluminum, copper), with low loss and high power processing capabilities, suitable for high-power scenarios (such as radar, satellite communication).
4. High stability: The metal waveguide structure has high mechanical strength and good temperature stability, making it suitable for harsh environments such as aerospace and military equipment.
1. Microwave communication system: Microwave diplexer can separate the transmitted and received signals on the same antenna port, thereby achieving full duplex communication, and is widely used in microwave relay communication, satellite communication and other fields.
2. Radar system: Millimeter wave diplexer can be used to separate the transmitted signal and the received signal, while ensuring high isolation between the two, which helps to improve the detection accuracy and reliability of the radar system.
3. Electronic countermeasure system: capable of effectively processing complex electromagnetic signals and playing a role in electronic countermeasure systems.
4. Microwave measuring instrument: Waveguide diplexer can be used in microwave measuring instruments to accurately measure the characteristics of microwave signals.
The waveguide duplexer, with its advantages of high power, low loss, and high isolation, is a core component in fields such as radar, satellite communication, and high-power broadcasting, especially suitable for scenarios with strict performance requirements and less volume limitations. Its disadvantage is high design and processing complexity, but it cannot be replaced in high-frequency and high-power applications.
Qualwave supplies multiplexer cover frequency range 17.3~31GHz. The microwave diplexers are widely used in many applications.
