Introduction to Common RF Connectors (2)

In the last article, we introduced the SMA connector. Usually, when selecting RF connectors, the main factors are its frequency range, impedance, withstand voltage, VSWR, size, etc. Therefore, different connectors have different properties and are suitable for different scenarios.There are several common types of RF coaxial connectors: N, SMA, L29, BNC, 2.92mm, 2.4mm, 3.5mm, 1.85mm, 1.0mm etc.N Ty……

There are 12 available frequency bands for TD-LTE in the world, which are 1900 ~ 1920MHz, 2010~2025 MHz, 1850~1910MHz, 1930~1990MHz, 1910~1930MHz, 2570~2620MHz, 1880~1920MHz, 2300~2400MHz, 2496~2690MHz, 3400~3600MHz, 3600~3800MHz, 703~803MHz.China has divided into 4 frequency bands for TDD, which are: 2010~2025MHz, 1880~1920MHz, 2300~2400MHz, 2496~2690MHz.Among them, Spectrum in the 2496-2690 MHz ……

3GPP Officially Defines U6G (6425-7125 MHz) Licensed Spectrum

At the 3GPP RAN#96 meeting held in Budapest, Hungary from June 6 to June 9, 3GPP officially defined the U6G (6GHz upper band, ie 6425-7125 MHz) as authorized spectrum, the frequency band number is n104, which clarified the corresponding network/terminal RF standards, and provided a standard basis for the subsequent industry chain research and development of 6GHz products.At the same time, the conf……

Introduction of base station and Remote Radio Unit

Base Station,generally refers to the “public mobile communication base station”, (abbr.: BS), the base station is used to provide signals to mobile phones. It usually consists of the following four parts:  Antenna-Feeder System:Responsible for signal transmission and reception, including antennas and feeders.Remote Radio Unit:Responsible for signal generation and extraction, which is the……
