​What should we notice when using the N-type connectors?

Since N-type connectors have been widely applicated in the 3G, it has been further used in communication. The impedance of it is 50 ohms. Due to its wide use, the domestically launched L16-type connector has the same structure as the N-type.

What is the performance of poor connector contact?

There are usually two manifestations of water ingress in-network connectors.

1. One is that the water in the N-type connector causes the water to enter part of the cable, which causes the dielectric coefficient of the intermediate insulation layer to change, and the cable attenuation increases, especially for high-frequency signals, which are reflected as high-end signals on the user side. Deterioration, more snowflakes, the amplifier output level slope is very small or negative on the mainline (if it is a sloping output);

2. Another performance is that water in the N-type connector will oxidize the connector, especially the common cable feed The power supply fails, which affects the normal operation of the entire downstream amplifier. At the same time, the slope becomes larger and the signal quality deteriorates.

What can lead to poor contact with the N-type connector?

The inner conductor of the existing cables is copper, and the outer conductor is aluminum-magnesium alloy wire or aluminum shell. Both the inner conductor and the outer conductor will oxidize in the air, especially in an environment with water. Copper can be oxidized at room temperature and high temperature to produce black copper oxide and basic copper carbonate, commonly known as patina, but basic copper carbonate can be decomposed into copper oxide at high temperatures. Both of these oxidation products are electrical insulators and insoluble in water, which have a great impact on the feed and signal transmission of the cable television transmission system.

What should we do when the N-type connector is used, unexpected failures sometimes occur?

For this reason, it is necessary to test as much as possible.

1. The rated performance values recorded in the product catalog, unless otherwise specified, are standard. When performing actual confirmation, please check the specification environment with the N-type connector.

2. Confirm under the same conditions as the actual use status.

The reference data recorded in the product catalog is made from the actual measurement values sampled in the production line graph.

The ratings and performance values recorded in the product catalog are the valuesof each test, and the combined conditions of each rated value and performance value cannot be guaranteed at the same time.

3. Correct selection of connectors

Please select the rated current, environmental conditions, and plug-in strips in combination with the environmental conditions during use connectors with suitable pieces, number of cores used, etc.

Applicable wires vary depending on the type of connector. Therefore, please confirm each product's applicable wires.

For immersion tin terminal products, the recommended board thickness is set according to the length of the terminal.

4. Please use the thickness recommended for the printed circuit board. Otherwise, it will cause poor welding.

If the N-type connector is not used correctly, some unexpected situations will occur. At this time, the quality of the N-type connector is particularly important. For many years, LenoRF has been a trustworthy supplier in the RF connector area. Rich product categories and high-quality after-sales service are the reasons why they are popular with customers.
