WAPA003 User’s Manual Introduction
Overview
WAPA003 Mini-PCI Module is designed to provide wireless communication for all wireless
device based systems. It communicates via the standard 802.11b/g protocols. The WAPA003
uses the AR5414 wireless chipset from Atheros. This module is connected to the PCI bus
through a Mini-PCI connector and special circuitry to allow for compatibility with either 3.3V or 5V PCI
signaling.
.
Features
 All-CMOS single chip for IEEE 802.11b/g compatible WLANs
 No external VCOs or SAW filters needed
 Baseband in-phase (I) and quadrature (Q) signals, converts them to the desired frequency,
and drives the RF signal off-chip
 Integrated low-noise amplifier (LNA)
 External PA and/or LNA can be used for special applications
 Advanced wideband receiver with best path sequencer for better range and multipath resistance
than conventional equalizer-based designs
 Extended tuning range (2.300-2.500) for worldwide use
 High speed UART with DMA supports data rates up to 1 Mbps
