Optichron

The firm's business centered on providing digital front-end (DFE) processors for 3G/4G LTE base stations. Its product portfolio included digital pre-distortion (DPD) processors and crest factor reduction (CFR) ICs. These products were developed to enhance the efficiency of power amplifiers in wireless infrastructure by mitigating nonlinear distortion. Optichron's technology was protocol-agnostic, enabling its use across various standards from GSM to WiMAX and LTE. The company also offered development tools, such as the DPD-CFR-DEV-30 platform, which provided a comprehensive solution for transmit signal chain compression and linearization. This platform allowed design engineers to improve power amplifier efficiency, thereby reducing system costs and operational expenses for their clients, which included original equipment manufacturers (OEMs) of next-generation base stations.

The company's offerings found applications in a range of fields beyond wireless communications, including software-defined radio, medical imaging, satellite communications, radar, infrared imaging, and test and measurement instrumentation. Optichron's business model was predicated on its fabless structure, focusing on the design and sale of its proprietary ICs while outsourcing the manufacturing process. The company's revenue was generated through the sale of these semiconductor products to its clients. A significant milestone in the company's history was its acquisition by NetLogic Microsystems in March 2011. The deal involved an initial cash payment of approximately $77 million to Optichron's stockholders. This acquisition was intended to broaden NetLogic Microsystems' product portfolio for the 3G/4G LTE base station market.
