A high-frequency coaxial connector (High Frequency Coaxial Connector) is a type of connector used to transmit high-frequency signals, primarily in radio frequency (RF) applications such as television, satellite communications, radar, and wireless networks. It is an important part of the high frequency transmission system, which can ensure the stability and reliability of the high frequency signal in the transmission process. Electrical Properties and Parameters The electrical properties and parameters of coaxial connectors include the following: 1. Frequency Range The frequency range of coaxial connectors is the range between the highest and lowest frequencies they can transmit. Frequency range is typically measured by signal loss, which is the reduction in signal power in the coaxial cable, and reflection loss, which is the loss of signal power when the signal is reflected. High-frequency coaxial connectors typically range in frequency from DC to 50 GHz. 2. Impedance The impedance of a coaxial connector is the resistance between the coaxial cable and the connector. It is an important parameter for coaxial connectors because impedance mismatch can cause signal reflection and loss. High-frequency coaxial connectors typically have two common impedances, 50 ohms and 75 ohms. 3. Insertion Loss Insertion Loss is the power loss of a signal as it passes through a coaxial connector. It is caused by resistance, inductance, and capacitance inside the connector. Insertion loss is typically measured in decibels (dB), and high-frequency coaxial connectors typically have an insertion loss of less than 0.5 dB. 4. Return Loss Return Loss is the power lost when a signal is reflected. It is caused by an impedance mismatch between the connector and the coaxial cable. The reflection loss is usually measured in decibels (dB), and the reflection loss of a high-frequency coaxial connector is usually greater than 20 dB. 5. Intermodulation Distortion Intermodulation Distortion refers to the nonlinear distortion generated by the signal inside the connector under high power signal. It causes unwanted signals to appear in the spectrum. Intermodulation distortion for high frequency coaxial connectors is typically less than -150 dBc. High Frequency Coaxial Connector Standards: 1. MIL-STD-348 This is a standard issued by the U.S. Department of Defense that specifies the interface and dimensions of RF connectors. The standard includes various types of connectors such as BNC, N-type, SMA, TNC, etc. The standard specifies parameters such as interface size, shape, sealing mode and impedance of connectors to ensure interchangeability and performance stability between connectors. 2. IEC 61169 This is a standard issued by the International Electrotechnical Commission (IEC) that specifies the design, performance, dimensions, and test methods for various types of coaxial connectors. The IEC 61169 includes sections covering common coaxial connector types such as BNC, N-type, SMA, TNC, and so on. This standard specifies the requirements of characteristic impedance, mechanical performance, electrical performance and environmental adaptability of connectors to ensure that connectors can meet the requirements of different applications. 3. DIN 47223 This is a standard issued by the German Industrial Standardization Committee (DIN) to specify the size, shape, and interface characteristics of coaxial connectors. The Din 47223 includes sections covering common coaxial connector types such as BNC, N-type, SMA, TNC, and so on. The standard specifies the requirements of connector interface size, impedance, mechanical properties and environmental adaptability to ensure that the connector can stably transmit high frequency signals in different applications. 4. GB/T 7395-2002 is a standard issued by China National Standardization Committee, which specifies the classification, size, shape, interface and characteristic impedance of coaxial connectors. The standard covers common coaxial connector types such as BNC, N-type, SMA, TNC, etc. The release of this standard is of great significance to China's domestic RF applications, and can provide a benchmark and guarantee for the production and use of coaxial connectors.
