Architecture
2.1 System Architecture
The LA-5137 is a modified type 1 CFA card. The LA-5137 Compact Flash Adapter CF card consists of all of the
integrated circuits necessary to provide WLAN transceiver functionality for the 2.4GHz and 5 GHz bands. The
Wireless LAN integrated Media Access Controller with Baseband processor directly interfaces with the Dual
Band Direct Conversion transceiver. With the addition of RF Front-end Module (FEM), the LA-5137 Compact
Flash Adapter card incorporates the WLAN chip set solution compliant with 802.11a/b/g standards.
Figure 2.1 Top-level LA-5137 CF Card architecture
The 40MHz crystal controlled clock provides the necessary clocks for both the PLL and the baseband & MAC
chip. The SDRAM provides additional memory to support SHoC (Self Hosted Client) operation. Not shown in
Figure 2.1 are the necessary voltage regulators that provide various supply voltages for the chips. The
regulators require 3.3V input supply.
The EEPROM is used to hold radio information including radio calibration information done at the automatic
manufacturing test step.

2.2 Hardware Environment
2.2.1 Introduction
The LA-5137 CF card can be used in handheld mobile devices to provide wireless network access. It
communicates using Radio Frequencies (RF) between two or more users or between a user and the wired
network. The module implements the IEEE 802.11a/g physical (RF) specification. The chipset used provides
for modulation, demodulation, spreading, and despreading of the RF signals.
2.2.2 Card Dimensions
The LA-5137 is a modified type 1 CFA card. See Appendix A, Product Mechanical Interface Drawing for
Mechanical Interface Drawing.
2.2.3 Card Physical
2.2.3.1 Operational Environment

2.2.4 Antenna Connectors (non embedded antenna)
The LA-5137-1002-WWR CF card (External Antenna Version) supports 2 RF connector (Hirose U.FL-R-SMT, or
equivalent). The antennas can be attached to the card through the connectors. There are two connectors on
the LA-5137-1002-WWR unit.
Architecture 2-3
NOTE: Antenna sharing with other radio modules is not supported on the LA-5137.
2.2.5 Antenna Requirements
For detailed antenna requirements, refer Chapter 7, Antenna Requirements (External Antenna).
NOTE: Regulatory Note: Many country regulations require special testing and reporting of antenna
performance or of the system with the antenna attached. Please check the appropriate regulatory
authority or contact Motorola for more information.
2.2.6 TX and RX Diversity
TX and RX diversity is only supported on the connector version of LA-5137 (LA-5137-1002-WWR).
