Lihewei: Self-developed power line carrier line drive power amplifier chip can be compared with similar foreign products

Jiwei network news (text / Zhang Lin) Recently, Lihewei said in an institutional survey that the power line carrier line drive power amplifier chip independently developed by the company is the first chip to achieve domestic substitution, and its product technical indicators can be comparable to similar foreign products. At present, the PA chips developed by the company are not only for their own use, but also for external sales. On the basis of stabilizing the supply chain, the company will continue to strengthen the market promotion of power line communication power amplifier (PA) chips, forming a wider range of applications and larger-scale domestic substitution. Power line communication power amplifier (PA) chips are usually used in conjunction with high-speed power line carrier communication chips.

It is reported that Lihewei, as an Internet of Things communication chip design enterprise, is a leading enterprise in domestic power line Internet of Things technology and power line communication chip.

At the same time, the application of Lihe microchip in photovoltaic has two aspects, one is photovoltaic panel monitoring, and the other is photovoltaic inverter control. For the construction of new energy photovoltaic power plants, the company has formed a complete set of photovoltaic monitoring solutions to help the digital upgrading of photovoltaic energy systems.

It is worth mentioning that the research and development of the new generation of Beidou multi-mode multi-standard navigation core chip of Lihe Micro is underway, and core algorithm schemes such as research capture and tracking have been overcome. This chip can be widely used in smart city construction, transportation, Internet of Things applications, power applications, mass applications and other fields.

Lihewei also said that in the era of the Internet of Things of the Internet of Things put forward comprehensive development requirements for communication technology, the traditional wireless connection technology, there are wall blocking, metal shell shielding, connection instability and other constraints, has been unable to meet the needs of the rapid development of the Internet of Things; in this context, the advantages of PLC gradually highlighted, PLC does not need wiring, can pass through the wall, high reliability, stability characteristics, better solve the Internet of Things scenario in the intelligent device communication connection pain point problem, It has gradually become one of the mainstream technologies in the Internet of Things market. Its products are mainly used in the power grid market, including smart home / whole house intelligence, smart street lights / smart lighting, energy efficiency management, high-speed rail and other fields in the non-grid market, has become a more effective Internet of Things "last mile" communication method.
