Sanan Optoelectronics is a company that has successfully produced gallium arsenide products in China, which is very important. In the 4G era, the demand for gallium arsenide PA is strong and the supply exceeds the demand: On the one hand, CMOSPA, which uses Si as its material, loses its competitiveness due to the limitation of physical properties that does not conform to the trend of 3G/4G high speed and wide bandwidth, it is expected that the market share of gallium arsenide PA will only be shared in the field of 2G low-end mobile phones in the future, and 4G mobile phones will be the world of gallium arsenide PA; On the other hand, because 2G and 3G technologies adopt 4 to 5 different frequency bands respectively, and 4G mobile phones need to support nearly 40 network frequency bands, as the number of frequency bands supported by terminals increases, the demand for gallium arsenide PA will also increase from 1-1 in the 3G era. 2 growth to 4- The popularity of 5 and 4G mobile phones and the increase in the number of PA per mobile phone will jointly create a strong demand for gallium arsenide. At present, gallium arsenide continues to be in short supply. LED is a successful past, and gallium arsenide is a brand-new beginning: Sanan LED business has moved towards the leader. In addition, the company has moved from a simple LED chip manufacturer to the second generation GaAs and the third generation GaN, it is currently a successful company in China that can mass produce gallium arsenide products. At present, there are already orders for Chengdu Yaguang more than 60 million. The company is working on integrated circuits (Microwave, power devices, etc) The technical reserves in the field are mature. At present, many interested customers have contacted each other and will increase their volume in 2015. The development of the company's business will enable the market to have a better understanding of the company, and the development of new business will not be inferior to LED, there will be continuous investment this year, and this one will surprise everyone this year. The new door has been opened: the opening of new business has led to the elimination of the factors that suppress the market value of Sanan, and the number of institutions that recognize the value of Sanan has gradually increased! When most companies in mainland China are still busy expanding production and improving luminous efficiency and yield, Sanan has moved towards gallium arsenide. There is no need to say more about Sanan's leading position in the industry. Gallium arsenide business will be rebuilt!
