The Journey of Huawei HiSilicon: From ASIC Design to Leading Chip Solutions

The Journey of Huawei HiSilicon: From ASIC Design to Leading Chip Solutions

In 1991, Huawei established its own ASIC design center, specifically responsible for designing “Application-specific integrated circuits (ASICs).” At that time, Huawei had only been founded for four years, with only a few dozen employees, and was financially strapped, nearly on the brink of bankruptcy. The foundational C&C08 digital program-controlled switch was still three years away. … Read more

Simplified SDR Radio Design for QRP HF Transceiver

Simplified SDR Radio Design for QRP HF Transceiver

Software Defined Radio (SDR) is a wireless communication technology that is based on software-defined radio protocols rather than through hardwired implementations. The bandwidth, air interface protocols, and functions can be upgraded via software downloads and updates without completely replacing the hardware. Today, we walk into a simplified SDR radio design with Uncle BG5WKP, which is … Read more
