How much do you know about coaxial cable? When you talk about coaxial cable, you will talk about the RF properties of coaxial cable. Do you know what the RF properties of coaxial cable are?The  Konnra Connectors  engineer will focus on introducing the RF properties of coaxial cables to you. We hope that you can master the RF properties of these coaxial cables through our explanation. The RF properties of coaxial cable mainly include six aspects: characteristic impedance, parasitic capacitance, transmission loss, transmission delay, return loss and rated power. The specific contents are as follows: 1. Characteristic impedance of coaxial cable It is an equivalent parameter in theoretical calculation, which reflects the measurement of the resistance degree of RF signal transmission when the wire transmits RF signal, and reflects the signal loss and signal delay of the transmission line at the physical ...

Many customers use products such as RF cable assemblies and converters and find that these products are particularly vulnerable to damage in the event of improper use, which is caused by improper use. So what to pay attention to when using RF cable assemblies and converters, the following  Konnra Electronics  engineers gave a detailed introduction to this problem. When we use RF cable assemblies and converters, there are six aspects that need to be brought to our attention in order to improve the life of the product. The details are as follows: 1) Do not use pliers to secure the RF connector. Almost every size of the RF connector has a suitable wrench, which of course refers to the plug of the hexagonal nut, while the round nut can only be removed by hand. Neither the nose pliers nor the vise can grasp the correct torque of the connector and can damage the connector. A torque wrench should be used to tighten the connector. Many hexagonal connectors with a sleeve size of 8 ...

Regarding the main performance PIM value (passive intermodulation) in the RF connector, you may only know that this performance value is available, but what is the use of it, and what effect it will have on the performance of the RF connector. How much loss is there in the signal transmission of the device. So Konnra Electronics will tell you what PIN (Passive Intermodulation) is? The PIM value (Passive Intermodulation) is a distorted signal generated by mixing two or more different frequency signals into a passive device due to the nonlinearity of the connection point or material. The generation of interference is related to the local downlink frequency, which can lead to an increase in uplink frequency noise when multiple systems share infrastructure. The impact of PIM on network quality is very serious, especially for broadband systems such as UMTS or LTE. PIM interference can lead to reduced receiver sensitivity, increased dropped call rate, increased access failure rate, pre...
