Haoda Electronics is mainly engaged in the research, development, design, production and sales of surface acoustic wave (SAW) filters. At present, more than 5% of the company's shareholders include Xiaomi Fund and Hubble Investment under Huawei Investment Holdings. In 2020, the company's biggest customer is Xiaomi Communication Technology Co., Ltd.
The main products of Haoda Electronics include SAW filters, diplexers and resonators, as follows:
Applications and technical capabilities of SAW filters and diplexers of Haoda Electronics in mobile phones: The operating income of Haoda Electronics in 20 18, 20 19 and 2020 is 654.38+65 million yuan, 206 million yuan and 332 million yuan respectively, and the net profit is 28.804 million yuan and 28.865 million yuan respectively.
IDM mode of Haoda Electronics is the mainstream mode of SAW filter industry at present. The manufacture of SAW filter needs to combine chip design and manufacturing technology closely, especially the manufacturing technology can ensure the realization of design parameters to a great extent. Only with high-level chip manufacturing technology can we meet the accuracy requirements of the filter in terms of electrode film thickness, dielectric film thickness, finger line width, finger shape and other related parameters, and we can produce a filter with good performance in terms of frequency, loss, standing wave and so on. Consistent with foreign leading manufacturers in the field of surface acoustic wave filters, such as Murata, Qualcomm (RF360), Sunshine Inductor, Sijiaxun, Weixun, etc., the company also adopts IDM mode to organize production, which has the ability to independently design, manufacture and package surface acoustic wave chips, and can realize independent control of the whole production process and efficient connection between the previous and subsequent processes. Haoda Electronics can design and manufacture high-performance surface acoustic wave RF chip products, and has a number of core technologies independently developed.
The company has CSP packaging technology for SAW RF chips. The size of filters and diplexers packaged by CSP can reach 0.9mm × 0.7mm, 1.6mm × 1.2mm, which meets the development demand of miniaturization in the industry, and the product specifications are basically consistent with those of leading foreign manufacturers. The company has WLP packaging technology for surface acoustic wave RF chips. The products of WLP packaging filters and diplexers can reach 0.8mm × 0.6mm,1.5 mm×1.1mm, which meets the demand of modular development in the industry and has been applied to smart phones of well-known downstream customers. The company has the ability of multi-product preparation, and has introduced SAW, TC-SAW and other surface acoustic wave filters, the highest frequency of which can be applied to 3.6GHz, which can meet the product requirements of downstream customers for multiple frequency bands; The company has high-power filter manufacturing technology. The high-power SAW filter developed by the company can withstand up to 35dBm, which is 3.75 times of the current conventional SAW filter, and can meet the technical requirements of 5G smart phones for high power. Haoda Electronics has large bandwidth filtering technology, which can achieve 7-30% super bandwidth. Some large bandwidth products have been successfully applied to 5G communication, which can meet the requirements of downstream customers to improve the wireless transmission rate.
At present, the main products of Haoda Electronics, such as SAW filters, diplexers and resonators, have been widely used in the communication field, with a frequency range of 30KHz-3.6GHz, wide application frequency band and diverse products.
Since its establishment, Haoda Electronics has continuously innovated and improved its technical level, and has a relatively complete design technology and manufacturing process for surface acoustic wave RF chips, which can provide high-quality surface acoustic wave RF chips that meet industry trends and meet customer needs. The company has always adhered to the business philosophy of independent research and development, innovation-driven, quality-oriented and customer-oriented, based on the research and development and upgrading of surface acoustic wave RF chip products, and is committed to overcoming the "stuck neck" technology monopolized by leading foreign manufacturers, and finally enhancing the brand awareness and industry influence of the company in the field of RF chips.
At present, the whole localization process of SAW filter is still in its infancy, and the overall technical level of domestic industry is still far from that of foreign leading manufacturers. The development of domestic SAW filter industry can not meet the domestic demand, and a large number of mobile phone filters still rely on imports. In recent years, international trade frictions occur frequently, and the downstream manufacturers of the company pay more and more attention to the independent and controllable supply of RF chips. Through continuous research and development and experience accumulation, some key performance indexes of SAW filters and diplexers in common frequency bands have reached the level of product parameters of leading foreign manufacturers, and their comprehensive performance is good. With the acceleration of the 5G process and the large demand for RF chips, Haoda Electronics will seize the opportunity to further enhance the product competitiveness and market share of SAW filters and diplexers by focusing on research and development, improving technology and expanding production capacity.
