Litong Communications launched the first high-performance 5G RF transceiver chip B20

      Litong Communications, a broadband RF transceiver chip research and development company, announced the launch of the first RF transceiver chip B20 that supports 200MHz bandwidth. As the first domestic RF transceiver chip that supports 200MHz bandwidth, B20 fully supports 5G applications, especially 5G mobile communication base stations, and takes into account usage scenarios such as private networks and special terminals.

     The RF transceiver chip is one of the core technologies that urgently needs to be broken through in the field of 5G mobile communication. It is the key to the low-cost, high-performance, and localization of radio frequency units in wireless communication. Self-sufficiency is almost zero.

     The performance parameters of B20 are comparable to those of similar products in the world, with a maximum bandwidth of 200MHz, covering 75MHz-6GHz applications, 2T2R, a maximum bandwidth of 200MHz for the receive channel, and a maximum bandwidth of 450MHz for the transmit channel. It has 2 independent 450MHz DPD observation channels, JESD204B interface, supports multiple chips Synchronous work, can completely replace imported products.

      Dr. Hou Weibing, Chairman of Litong Communications, said: "I am very pleased to announce the success of the B20 tapeout today. The third-party test results show that all performance and functions are in line with expectations, and can fully meet the application requirements. Some indicators even exceed expectations. The first RF transceiver chip that truly supports 5G full standard is the result of the efforts of the Litong communication team for many years. As a milestone product of the company, it is believed that it will soon be applied to various small base stations and comprehensively promote the development of communication base stations. localization process.”

      B20 has complete independent intellectual property rights. So far, it has applied for 27 invention patents, which are the technical achievements condensed by the experienced R&D team of Litong Communications over the years.

      Deputy General Manager Lei Weilong added: "Litong Communications has always been in close contact with small cell manufacturers and major operators, which is of great help to us in understanding market demand. At the same time, users and partners also give high Attention, this also reflects the prospect of the small cell market and the urgent demand of small cell manufacturers for localized solutions. With the launch of B20, localized RF chips can also meet the application needs of small cells. In 2022, Litong Communications will We will do our best to connect with various manufacturers on B20, and apply B20 to various small cell solutions as soon as possible.”

      RF transceiver chips are a large market with a scale of more than 30 billion US dollars. In the future, with the rapid development of various industries such as the Internet of Vehicles, Industrial Internet, Star Internet, Internet of Things, etc., it will be widely accompanied by a large number of 4G+, 5G, 6G, Wireless communication applications such as satellites, these applications will explosively promote the rapid growth of the market demand for RF transceiver chips in the future. The B20 series and ZL series of RF transceiver chips independently developed by Litong Communication can be widely used in various wireless RF communication fields, such as 4G/5G base station RF solutions, IoT end-to-end RF solutions, and V2X vehicle-road collaboration RF solutions , 6G satellite intermediate frequency transceiver solutions and other high-speed wireless radio frequency communications, the market capacity space is huge. At present, Litong Communications is actively working with various communication operators, equipment manufacturers, and relevant upstream and downstream localized chip manufacturers to jointly promote the localization of domestic 5G small base station equipment. application.
