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 form

factor.
