说明：  CC2420是Chipcon公司推出的首款符合2.4GHz IEEE 802.15.4标准的射频收发器（RF transiver）。它只需要极少外部元件，其选择性和敏感性指标超过了IEEE 802.15.4的要求，可确保短距离通信的有效性和可靠性。并且支持最高达250kpps的数据传输速率，可实现多点对多点的快速组网。
(Chipcon CC2420 is the company's first with 2.4GHz IEEE 802 .15.4 standard RF transceiver (RF transiver). It requires very few external components, selectivity and sensitivity of the indicators over IEEE 802.15.4, to ensure that short-range communications effectiveness and reliability. Support 250kpps maximum data transmission speed can achieve more rapid point-to-multipoint network.)
