Atmel 公司的AT86RF230是低功耗的2.4 GHz无线电收发器,是真正的SPI到天线的解决方案,设计用于ZigBee/IEEE 802.15.4.单片内集成了除天线,晶体和去耦电容外所有的RF关键元件. AT86RF230可编程输出功率从-17dBm到高达 3dBm,接收器灵敏度为-101dBm,工作电压从1.8V到3.6V,并集成了内部稳压器,主要用在2.4 GHz IEEE 802.15.4 和ZigBee系统, 6LoWPAN 和RF4CE系统,无线传感器网络,工业控制,家庭和建筑物自动化以及消费类电子和PC外设等.本文介绍了AT86RF230主要特性, 方框图, 应用电路图和RZ600评估板特性以及无线电电路图和USB适配器电路图.
The AT86RF230 is a low-power 2.4 GHz radio transceiver especially designed for ZigBee/IEEE 802.15.4 applications. The AT86RF230 is a true SPI-to-antenna solution.All RF-critical components except the antenna, crystal and de-coupling capacitors are integrated on-chip. Therefore, the AT86RF230 is particularly suitable for applications like:
• 2.4 GHz IEEE 802.15.4 and ZigBee systems
• 6LoWPAN and RF4CE systems
• Wireless sensor networks
• Industrial control, sensing and automation (SP100, WirelessHART)
• Home and building automation
• Consumer electronics
• PC peripherals
The AT86RF230 can be operated by using an external microcontroller like ATMEL’s AVR microcontrollers. A comprehensive software programming description can be found in the application note AVR2009 “AT86RF230 – Software Programming Model”.
This single-chip radio transceiver provides a complete radio transceiver interface between the antenna and the microcontroller. It comprises the analog radio transceiver and the digital demodulation including time and frequency synchronization, and data buffering. The number of external components is minimized such that only an antenna, a crystal and four decoupling capacitors are required. The bidirectional differential antenna pins are used for transmission and reception, so that no external antenna switch is needed.

RZ600评估板
The RZ600 evaluation kit enables development, debugging and demonstration of IEEE 802.15.4 compliant wireless applications such as ZigBee and 6LoWPAN. The kit is FCC certified and contains evaluation boards for AT86RF212 and the AT86RF23x families of RF transceivers covering the regional 700/800/900MHz and worldwide 2.4GHz ISM bands for use with STK600.
The kit also contains two USB adapters equipped with UC3A 32-bit AVR microcontrollers for standalone point-point or packet sniffer operation.
