Hangzhou Zuolan Microelectronics Technology

Hangzhou Zuolan Microelectronics Technology Co., Ltd. is a high-tech enterprise specializing in the Micro-Electro-Mechanical Systems (MEMS) field, established in November 2016. The company focuses on the research, development, and sale of high-performance radio frequency (RF) filters, duplexers, and RF front-end modules. Its products are designed to address multi-frequency adaptation issues in mobile terminals, aiming to achieve near-zero RF loss across various frequency bands. The company was founded by overseas high-level returnees, including Dr. Zhang Shumin, who serves as the general manager. The R&D team comprises experts in materials science, acoustics, and electrical engineering, with a significant portion holding postgraduate degrees.

The company's product portfolio caters to different frequency bands to meet the demands of the 5G era, including conventional Surface Acoustic Wave (SAW) filters for low-frequency communication, Temperature-Compensated SAW (TC-SAW) for mid-frequencies, and Film Bulk Acoustic Resonator (FBAR) for high frequencies. In 2020, Zuolan Microelectronics was among the first in China to launch and mass-produce TC-SAW products, filling a domestic gap for high-end RF filters. The firm also develops various RF front-end module solutions like DivFEM, FEMiD, PAiD, and PAMiD to enhance performance and save PCB space in 5G terminals. Its products are utilized by several well-known domestic mobile ODM and communication terminal manufacturers, with shipments reaching nearly 100 million units.

Zuolan Microelectronics operates on a model that integrates a global supply chain with its in-house R&D to manage the entire process from development to production. The company has received significant financial backing, including a recent B+ funding round and a series of亿元-level financings from investors like Shenzhen Pengchenxun Da, Wuxi Guolian Fund, and existing shareholder Yihe Capital. This capital is directed towards increasing R&D investment, expanding mass production, and broadening its product range. The firm holds over 150 core patents and operates advanced laboratory facilities. It has established a comprehensive operational base in Changzhou, integrating R&D, testing, and sales to address growing market demands.
