Coaxial cable remains one of the most popular mediums for transmitting information, and it looks like it's here to stay. Developed in 1880 coaxial cables were devised by British engineer and mathematician Oliver Herside and patented to help develop long-distance communications. For example, coaxial cables still play an important role in the field of communication, especially in the field of mobile 4G.
With so many options, it's easy to get overwhelmed by the choice, so here's my more concise guide to using coax connectors.
Here are my top 10 things to consider when choosing a coaxial cable connector.
1. Operating frequency
Frequency is the number of times an exponential periodic action occurs in one second. The SI unit for measuring frequency is Hertz. RF connectors are classified into systems or systems. One column per system operates within the set limits. Based on its wide frequency range of 0-18 GHz, the SMA connector is an ideal connector for many applications.
2. Character resistance
Impedance matching is an important consideration in the design process. The SI unit for measuring impedance is the ohm. Plenty of connectors run between 50-95 ohms and follow the video. The RF connectors used, such as BNC and F connectors, typically run at 75 ohms and most 2400 MHz applications run at 50 ohms.
3. Insert damage
Insertion damage, expressed as a dB ratio relative to the efficiency of the transmitted signal, refers to the efficiency of the signal lost by equipment drying up during transmission. . The further the signal has to travel, the greater the reduction. Many factors can affect insertion damage, including coaxial cable type and length. The ultimate goal of any transmitter connector is to minimize reduction.
If the source transmits with efficiency PT and the load receives with efficiency PR, the insertion damage in dB is given by
The low-loss cable developed by Times Microwave is gaining popularity as its reduced price makes it a natural choice for many applications, such as high traffic in antenna and signal applications.
4. Efficiency processing
Most RF connectors used in the telecommunications industry can safely operate at voltages up to 500 volts. Usually the larger the connector, the higher the functional handling capability. For example, N handles voltages up to 2,700 volts.
5. Gender
In the field of RF connectors, plugs are often referred to as "external bolt thread" and have a bolt on the inside. Jacks are usually "female", with bolts on the outer surface. And not all bolts are bolt-to-rod. MCX connector collection with the lapping mechanism. A good rule of thumb is that the plug accommodates the pin. The exception is reverse polarity connectors with female and female center contacts, which are most commonly used in wireless networking systems.
6. Shape
Since the development of the first UHF connector in 1930, coaxial cable connectors have become smaller and smaller. The miniature IPX connector profile is only 2.5 meters and you can't hide your ears! There is a power tradeoff between size and power handling.
7. Durability
Many factors can affect the durability of a radio frequency connector. How often do connectors connect and disconnect? The highest number of scheduled mating times for many radio frequency connectors is Guo 5. For outdoor or indoor? What temperature will the connector withstand?
8. Environmental investigation
The main factors to keep in mind are durability and environmental factors. Mil-Spec RF connectors are tested to simulate environmental conditions such as vibration and humus. Usually expressed in MIL-STD-XXX format.
9. Lloyd's way
Machining associated with RF connectors is another reason related to durability. The universal screw interface provides a secure connector for the SMA connector, but the lock function is provided by the NC, which is not convenient for the video to break open the connection. Snap-in mating is becoming more common in more space-critical applications.
10. Cost
Most of the time, despite finding the perfect coaxial connector for your RF application, the final decision comes down to forecasting. relatively low.
These considerations serve as a reference summary of the top considerations when selecting a coax connector for your application. Between these factors often occurs, still yes. Each has its own set of requirements. Decide what is best for your project.
