Section One: Introduction
AMBIT MINIPCI 3B WLAN/Bluetooth Combo Module complied with IEEE 802.11b 11Mbps
Standard. The WLAN/Bluetooth application is implemented via a Intersil Prism 2.5 RF
circuit. This RF circuit is developed for Wireless LAN application complied with IEEE
802.11b 11Mbps standard in ISM band. It can be used to provide a variety of low-cost
wireless network interfaces to build your wireless connection via simply SMT procedure to
speed the time to market. Three Intersil’s chips are implemented including ISL3984, ISL3685,
HFA3783. With Bluetooth technology, the Bluetooth part can achieve internet connection
rates up to 721 kbits/s. The Notebook communicate with Bluetooth by MiniPCI Interface
Reserve pin. The WLAN/Bluetooth combo card mechanical complies with MINIPCI 3B from
factor.
