RF connectors belong to mechatronics products and are usually installed on cables or instruments to achieve electrical connection transmission or separation. When purchasing RF connectors, they can be purchased based on the electrical performance indicators required for actual applications. The main electrical performance indicators of RF connectors include:
1. Characteristic impedance: Characteristic impedance is a very important basic parameter of RF connectors, which directly affects the voltage standing wave ratio, operating frequency band, insertion loss and other indicators of RF connectors. Generally speaking, the standard impedance of RF connectors is 50 Ω.
2. Voltage standing wave ratio: Voltage standing wave ratio refers to the ratio of the maximum amplitude of voltage (current) on the transmission line to the minimum amplitude, which is the main basis for judging the transmission performance of RF connectors. Generally speaking, the lower the better, but the corresponding cost will also increase.
3. Frequency range: The frequency range parameters of RF connectors must be paid attention to in applications such as high frequency and high speed. The frequency of RF connectors can be divided into several levels, such as 1-6GHz, 0-18GHz, 20GHz, 27GHz, 40GHz, 50GHz, 67GHz, 110GHz, and even higher.
4. RF insertion loss: Insertion loss is an important indicator of transmission systems, but in reality, the loss of RF connectors is very small compared to cables. At 2GHz, the insertion loss of SMA RF connectors is only 0.03dB.
5. RF leakage: With the development of the entire system, the requirements for signal transmission quality are becoming higher and higher, and the RF leakage indicators of connectors are also receiving more attention. If the RF leakage value is relatively large, it not only indicates that the energy transmission loss of the product is large during use, but also the anti-interference ability of the product is poor. The usual testing frequency is 2-3GHz, and the required indicators are 60-90dB.
