TI 公司的CC1120是全集成的868/915MHz单片无线电收发器，主要用在窄带超低功耗无线系统，无线计量和无线智能电网（AMR和AMI），IEEE 802.15.4g系统，家庭和建筑物自动化，工业控制，无线保健，无线传感器网络和有源RFID，私人移动无线电等。本文介绍了CC1120开发套件主要特性和组成，SmartRF收发器评估板(TrxEB)主要特性，和EM连接图，SmartRF TrxEB架构图以及SmartRF TrxEB 1.3.0和1.5.0电路图。

The CC1120 development kit provides a complete hardware performance testing and software development platform for TI’s Sub-1 GHz Performance Line devices. The development kit comes with a pre-programmed packet error rate test. RF range and robustness can be tested with different RF settings, and power consumption can be measured easily. This kit supports 868MHz and 915MHz. Additionald Evaluation Module Kits can be purchased separately to support other frequencies.

This kit supports 868MHz and 915MHz. Additionald Evaluation Module Kits can be purchased separately to support other frequencies.

The kit includes the SmartRF Transceiver Evaluation board (TrxEB), which has a number of useful features for development of prototype software, as well as USB connectivity making it possible to connect the board to a PC and control the radio from SmartRF Studio. In short, the TrxEB includes

MSP430F5438 MCU

USB interface

128 x 64 dot matrix LCD

3 axis digital accelerometer

Ambient light sensor

The software examples provided with the kit can be used as a basis for working with the Transceiver Evaluation Board and the connected radio.

SmartRF收发器评估板(TrxEB)

The SmartRF TrxEB is a flexible test and development platform that works together with RF Evaluation Modules from Texas Instruments.

An Evaluation Module is a small RF module with RF chip, balun, matching filter, SMA antenna connector and I/O connectors. The modules can be plugged into the SmartRF TrxEB which lets the PC take direct control of the RF device on the EM over the USB interface.

Currently, SmartRF TrxEB supports:

- CC1120EM

- CC1121EM

- CC2520EM

- CC1101EM

- CC1100EM

- CC1100EEM

- CC110LEM

- CC113LEM

- CC115LEM

SmartRF TrxEB is included in e.g. the CC1120 development kit. Some of the above EMs comes in variants combined with a RF front-end such as CC1190 or CC2590/CC2591. Such variants are called combo EMs and are also supported by the SmartRF TrxEB. See chapter 8 for details on how to use SmartRF TrxEB rev. ≤1.5.0 to control a combo EM using SmartRF Studio.
