A Circuit Design and Realization of a Dual-Mode Wireless Network Card based on Mini PCI-E

介绍了一种基于mini PCI-E接口的WiFi/WAPI网卡电路设计方案,包含硬件设计、软件设计和测试方案设计。双模网卡芯片选择华大电子的HED05W01SU基带芯片和诺达的AL2230S射频芯片。硬件介绍了射频接口、基带接口和mini PCI-E接口电路;软件介绍了网卡驱动和配置界面的设计;最后根据GB15629.11国家标准对开发的双模网卡进行了测试验证,测试结果达到标准要求。该网卡设计方案具有集成度高、接口简单、价格低廉、使用方便等特点。

A WiFi / WAPI dual-mode WLAN card circuit design based on mini PCI-E specification is introduced, whose implementation is based on HEDOSW01SU chip and AL2230S chip, including hardware design, software design and test program. In the aspect of hardware design, the RF chip inter- face design, the baseband chip interface design and the mini PCI-E interface design are included. In the aspect of software design, the driver software and the management software for WLAN card working in Windows OS environment are presented. Based on the GB15629. 11 specification, the test program is added for verifying the WLAN card development, and the test results meet the specification requirements. High integration, simple interface, inexpensive and easy to operate is the WLAN card marked properties.
