LS Research公司的TiWi-SL是高性能2.4 GHz 802.11 b/g WLAN模块,包括了必需的PHY,MAC和支持WLAN应用的网络层。模块和IEEE 802.11 b/g兼容,WLAN发送功率+19.0dBm或+15dBm,WLAN灵敏度为-85dBm或-70dBm,工作电压2.9V- 3.6V.主要用在HVAC控制,智能电网,传感器网络,医疗,家庭自动化和监测。本文介绍了TiWi-SL模块主要特性, 模块方框图,评估板电路图和材料清单以及片状天线和双极天线指标与相应的参考设计电路。
The TiWi-SL is a high performance 2.4 GHz WLAN module that contains an IP networking stack in a pre-certified footprint. The module includes the necessary PHY, MAC, and network layers to support WLAN applications through a simple SPI connection to host microcontrollers or other embedded processors. Need to get to market quickly? Not an expert in 802.11. Need a custom antenna? Would you like to own the design? Would you like a custom design? Not quite sure what you need? Do you need help with your host board? LS Research Design Services will be happy to develop custom hardware or software, or assist with integrating the design.

This document covers a description of the EM board and its features and a brief tutorial on how to operate the module EM board. The TiWi-SL EM “Evaluation Module” Board is an evaluation platform for the LS Research TiWi-SL 802.11 b/g Wi-Fi module. Communication between the TiWi-SL module, which is a slave, and the host device is through an SPI interface. The TiWi-SL EM Board contains an on board chip antenna, and is intended for evaluation purposes when used in conjunction with the Texas Instruments MSP-EXP430FR5739 Experimenter Board. 20120221110111276.gif 图2.实验板和TiWi-SL EM板外形图 20120221110113618.gif 图3.TiWi-SL EM板电路图 TiWi-SL EM板材料清单(BOM): 20120221110115373.gif TIWI-SL天线设计指南 The purpose of this document is to provide details regarding the design and integration of certified antennas to the TiWi-SL module. It covers both a PCB mounted chip antenna as well as an externally mounted dipole antenna. It will inform the designer as to the required PCB layout details, and provide expected performance specifications. 片状天线指标: 20120221110117281.gif 2012022111012229.gif 图4.片状天线参考设计电路图 The LSR 001-0001 Dipole Antenna is used in conjunction with the LSR 080-0001 U.FL to Reverse Polarity SMA Cable, and the Hirose PCB mounted U.FL connector, to provide an externally mounted antenna solution for the LSR TiWi-SL Radio module. 双极天线指标: 2012022111012246.gif 20120221110123270.gif 图5.双极天线参考设计电路图 详情请见: TiWi_SL_EM_Board_User_Guide.pdf(505.82 KB)2012-2-21 22:14 上传 -1 和 TiWi_SL_Datasheet.pdf(755.77 KB)2012-2-21 22:14 上传 -1 以及 TiWi_SL_Antenna_Design_Guide.pdf(1.25 MB)2012-2-21 22:14 上传 -1 |
