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 802.11a/b/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
y All-CMOS single chip for IEEE 802.11a/b/g compatible WLANs
y No external VCOs or SAW filters needed
y Baseband in-phase (I) and quadrature (Q) signals, converts them to the desired frequency,
and drives the RF signal off-chip
y Integrated low-noise amplifier (LNA)
y External PA and/or LNA can be used for special applications
y Advanced wideband receiver with best path sequencer for better range and multipath resistance
than conventional equalizer-based designs
y Extended tuning range (2.300-2.500 & 4.900-5.850 GHz) for worldwide use
y High speed UART with DMA supports data rates up to 1 Mbps
