Professional Manufacturer For RF&Microwave Solutions

N RF Connectors are irreplaceable components that connect circuits in electronic devices to transmit current. The basic structure of the connector can be divided into four parts: contact, insulator, shell, and accessories.

Contact parts: the positive contact parts and the negative contact parts, through the insertion of the yin and Yang two contact parts to complete the electrical connection. Contact is the core part of the N-type connector, mainly to play the role of electrical connection.

Insulator: can make the contacts in the required position and spacing arrangement, and to ensure that the insulation between the contacts and between the shell and the contacts. Insulator is also called the base, mounting plate, the insulation material is required to have good insulation resistance, voltage resistance performance, easy to process.

Shell: As the outer cover of the N-type connector, mainly for the insulation installed inside the mounting plate and pins to provide mechanical protection.

Accessories: There are two types of structural accessories and mounting accessories. Structural accessories - snap rings, coupling rings, cable clamps, locating pins, guide pins, sealing rings, gaskets, etc.; mounting accessories - screws, nuts, screws, spring rings, etc.

N RF Connectors are usually tested and inspected on the finished product after manufacturing is completed.

Electrical Properties of N RF Connectors.

The actual electrical properties depend on the performance of the cable, the contact of the cable, the geometry of the connector, the contact of the inner conductor, etc. The maximum frequency of the coaxial cable must be the maximum frequency of use of the weakest component in the transmission line, because it depends on all components and not on one component. For example, if the frequency of an RF connector is 10 GHZ, the frequency of the cable connected to it is 5 GHZ, and the maximum frequency of this component is 5 GHZ. The combination of all factors determines the frequency of the entire transmission line.

N RF Connectors trends.

1, miniaturization: With the miniaturization of the whole system, the volume of N RF Connectors is getting smaller and smaller.

2, high frequency: HP in the United States as early as a few years ago, the frequency has been introduced to 110GHz N RF Connectors.

3, multi-function: In addition to the role of the bridge, both processing signal functions, such as filtering, phasing, mixing, attenuation, detection, limiting, etc..

4, low standing wave, low loss: to meet the needs of weapons systems and precision measurement.

5, large capacity, high power: large capacity, high power mainly to adapt to the development needs of the information superhighway.

6, surface mount: mainly adapt to the development needs of SMT technology (surface mount technology), and help to simplify the design of wiring structure of multilayer printed board.
