SMA connectors are generally connections between pin contacts and hole contacts. We know that the pins or terminals of components generally have a layer of plating, such as lead-tin alloy plating, pure tin plating, nickel plating, silver plating, silver plating palladium alloy, gold plating, and so on. So the contact between components is actually these plating...

SMA Connector Basics The SMA connector is a subminiature coaxial cable connector whose name is derived from the Sub-Miniature A connector. It finds many applications for providing connectivity to RF components within devices that require coaxial connectivity. It is often used to provide RF connections between circuit boards...

The ipex RF cable assembly is a combination of RF coaxial connectors and flexible cables or semi-rigid and semi-flexible cables. It is widely used in microwave equipment and digital communication equipment. In rfid systems, a large amount of radio frequency is also required. Cable assemblies, such as the connection between the reader and the antenna...

I believe that many of my friends have a little knowledge or a deeper understanding of 5G antennas. So what is active testing? We must first understand what is an active antenna. Active antenna: (straight point: it is the antenna with complete components and can be used normally) The internal structure of the active antenna is complete, and the antenna mode...

5G commercial use: antenna technology is the foundation Since the commercial use of 4G licenses in my country, as of the first half of 2015, the 4G communication network has fully covered areas above the township level. At present, the construction of mobile communication network continues to accelerate. According to statistics, as of September 2015, my country's mobile...

5G mobile phone antenna characteristics and technology (1) 5G terminal antennas are very sensitive to surrounding metals. Since the wavelength of millimeter waves is very short, the interference from metals is very severe. Printed circuit boards (ie PCB boards) need A clearance of 1.5mm should be maintained between metal objects. (2) 5G days...
