Description

The SMA connector is a semi-precision sub-miniature RF and microwave connector that is extensively used, especially for RF connections within electronic systems for frequencies up to 18 GHz and sometimes more.

The SMA connector comes in a variety formats, male, female, straight, right-angled, bulkhead fitting and many more enabling it to meet most requirements. Its sub-miniature size also enables it to be used, even within relatively small items of electronic equipment.

Although now well established, the SMA connector is likely to see its use extended as many new RF systems see their operating frequencies extending well into the microwave region.Although SMA connectors look very similar to the standard household connectors used for domestic satellite TV and other similar applications. These domestic connectors are called F type coax connectors and they have a 75Ω impedance. They have a different diameter and cannot mate with SMA connectors – they would need a special adaptor and then there would be an impedance mismatch.

What advantages do Waterproof circular connectors bring?2022-09-18T23:54:20+08:00

First, Contact resistance.

This is a waterproof round ConnectorFor the performance of common electrical equipment, the contact resistance of high-quality connectors should be relatively stable. Generally speaking, the change of resistance ranges from a few milliohms to tens of milliohms.

Second, the insulation resistance of waterproof plug.

Waterproof round ConnectorThe insulation resistance is also one of the main indexes of its electrical performance. Insulation resistance can measure the insulation performance between the contact parts of the connector and the shell. In industry regulations, the insulation range ranges from hundreds of megaohms to thousands of megaohms.

In addition, the waterproof circular connector also has reflection coefficient, characteristic impedance, current and other coefficients, characteristic impedance, current and so on.

Is Sinrui’s gold plating always lead-free and RoHS compliant?2022-09-18T23:54:03+08:00

Yes, Sinrui’s gold plating is always lead-free and RoHS compliant (pre-plated or in house plated).

Will Sinrui provide a formal RoHS CoC (Certificate of Compliance) for their products?2022-09-18T23:53:27+08:00

Yes, upon request, Sinrui will provide a formal CoC. Please provide Company name and address as well as Company contact and contact information of the person requesting the CoC along with valid Sinrui part numbers to our General Technical Support Group.

What is the optimal signal-to-ground ratio?2022-09-18T23:53:03+08:00

A signal-to-ground ratio of 1:1 is usually optimal, but for connectors with large pin arrays signal-to-ground rations of less than 1:1 may be required for reliable high speed single-ended operation.
