The Biggest Microwave, RF and Antenna Event in China China International Conference & Exhibition on Microwave and Antenna (IME/China), which is the largest and most influential Microwave and Antenna exhibition in China, will be a good platform and channel for technical exchanges, business cooperation and trade promotion between global Microwave and Antenna products & technology suppliers a……

As the 3GPP RAN conference announced the freezing of the 5G Release 17 (abbr.: R17) standard, it means that the 5G RedCap new technology standard for the medium and high-speed Internet of Things is ready, and the future will further expand the intelligent new scene of the 5G Internet of Things. “RedCap, the full name of Reduced Capability NR, literally translates to the meaning of reducing NR capa……

Recently, it was learned from the Shenzhen Bureau of Industry and Information Technology that as of now, the number of 5G base stations in Shenzhen has exceeded 70,000, and the number of 5G users has exceeded 13 million. With its 5G network coverage density and user proportion rank among the top in major cities, It provides a solid support for the high-quality development of Shenzhen’s digital eco……

In last article, we introduced the concept and common applications of the POI system. This article will focus on the POI system design and product features. The common design of POI System：1) Two-way co-channel mode for signal sending and receiving. 2)One-way split mode for signal sending and receiving. POI system product features:1. Compatible with multiple systemsMeet DTV, 2G, 3G,……

POI is the abbreviation of POINT OF INTERFACE, that is, a multi-system integration platform. It is mainly used for multi-band and multi-signal combination to achieve compatible coverage of multi-network signals. It realizes multi-system, multi-band signal transceiver and cable transmission: and is able to meet the versatile requirements of DTV, 2G,  3G, 4G,  5G (can support LTE MIMO) etc. The……

LC FiltersThe LC filter is a filter composed of appropriate capacitors and inductors. It could be designed to realize low-pass, band-pass, high-pass, and band-stop filters.Pros: Small size, low cost, long parasitic passbandCons: The insertion loss is high, the out-of-band selection performance is poor, and the power capacity is small.In addition, the inductance in the LC filter adopts the method o……
