The radio frequency coaxial connector (hereinafter referred to as the RF connector) is usually regarded as a component installed on the cable or installed on the instrument as a component for electrical connection or separation of the transmission line. It belongs to mechatronics products. Simply speaking, it mainly serves as a bridge. Compared with […]

1. BNC Characteristic impedance The characteristic impedance of BNC radio frequency connectors is 50Ω and 75Ω. Many series of connectors have both 50Ω and 75Ω specifications. Generally speaking, 50Ω connectors are mostly used for high-frequency and high-performance products; 75Ω connectors are mostly used for products with lower frequencies, and the frequency is mostly below 4GHz, […]
An omnidirectional antenna, that is, it shows uniform radiation in 360° on the horizontal pattern, which is commonly referred to as non-directional, and shows a beam with a certain width on the vertical pattern. In general, the smaller the lobe width, The greater the gain. The omnidirectional antenna is generally used in the mobile communication […]
Wondering whether it’s faster with 2 antennas or 4 antennas? Many find themselves caught in this dilemma when selecting a router. Let’s delve into this conundrum using the Huawei Router A1 as an example. Which offers better speed, internal or external antennas? To address this query, it’s essential to grasp the current landscape and differences […]
It has been almost a hundred years since the birth of the walkie-talkie, half a century before the invention of the mobile phone. But in the last century, mobile phones have evolved from the former “big brother” to today’s smart phones, and the walkie-talkie is still the same stupid, black and thick old one, and […]
What is wireless network Wireless network, as the name implies, is a way to build a network without relying on a network cable. It is mainly realized by using wireless communication technology. There are mainly two ways of implementing wireless networks (such as 4G, 3G or GPRS) through mobile communication networks and wireless local area […]
Wireless bridges must be used in conjunction with antennas. There are two common wireless bridges and antennas, one is external, the other is internal. As the name suggests, the built-in antenna is installed inside the housing of the wireless bridge and is invisible on the surface. The built-in antenna is usually small and can be […]
An attenuator is a two-port electronic device used in a circuit to reduce the amplitude of a specific signal without causing too much distortion in the output. In view of the fact that amplifiers are mostly used to increase the gain coefficient, when it is necessary to reduce/decrease the signal amplitude, an attenuator is needed. […]
Coaxial cables are higher-grade cables designed to meet specific impedances and transmit higher-quality signals, which can work at higher frequencies and data rates. A coaxial cable contains two conductors located in the center of the same axis. The coaxial cable contains an internal signal wire, which is usually made of copper and wrapped with a […]
SCSI connectors connect devices that run small computer system interface standards and protocols. SCSI was developed for computer-based communications, usually communications between printers, scanners, hard drives, and disk drives. There is no standard connector size or pin count, but the most common is the ultra-small D form. This means that there is a protective metal […]
