RadRock launched a 5G N41 RF module with integrated N41 full-band WLP filter
2020.03.05
N41 is called China Mobile's main frequency band, and its advantages of wide frequency spectrum and wide coverage are called "golden frequency bands" by industry professionals. N41 has the characteristics of lower frequency (2.6G<3.5G<4.9G), so as to obtain better cell coverage; at the same time, N41 is the same as or close to the current 4G B41 frequency band, which means that the base station side can be upgraded Quickly support 5G N41 network deployment without building new base stations, thus accelerating the 5G industry process. With the gradual popularization of 5G networks, the design of 5G smartphones will be standard equipped with 5G frequency bands such as N41/N77/N79. The N41 frequency band is regarded as the key coverage frequency band of China Mobile. China Mobile requires the N41 to be configured with 2T4R to increase the transmission rate and coverage depth for models of 3,000 yuan and above. The importance of the N41 frequency band is self-evident.
As a well-known supplier of 5G RF devices in the industry, RadRocklaunched the RF power amplifier filter module (PAMiF) RR58041-11 and 5G RF power amplifier module (PAM) RR59041-11 supporting the N41 band earlier.
RR58041-11 is the first domestic PAMiF product that supports the 5G N41 frequency band (2496MHz~2690MHz) and Power Class2. Built-in power amplifier, transceiver switch, CMOS controller and high-performance filter in the module.
Among them, the RF PA adopts a differentiated architecture design, PAE is significantly improved, and the current performance is relatively excellent. RR58041-11 is also the first domestic PA manufacturer to adopt Flip chip filter technology, which can improve insertion loss, reduce size, enhance heat dissipation and improve reliability.
Founded in April 2017, RadRock is an RF front-end supplier, focusing on the R&D and sales of RF front-end products for communication terminals to meet the needs of mobile phone manufacturers for RF front-end products in the 4G, 5G and Internet of Things markets. In January 2020, RadRock completed a series B financing of 150 million yuan, and received investment from strategic partners and investors such as Huaqin Communications, Shunwei Capital and Hengxin Huaye, and co-invested by Shanghai Linxin Investment, an old shareholder in this round
Combined with the RR88643-81 supporting HPUE and the RR88643-91 supporting single-chip EN-DC, Ruishi Chuangxin has basically completed the layout of the 5G RF front-end chip. In the first year of commercialization of the 5G industry, Ruishi Chuang Chip will work with upstream and downstream partners in the industry chain to continue market-driven technological innovation, provide more innovative and cost-effective 5G RF front-end products, and help accelerate the 5G commercialization process.
