8168B-MCU Wireless-03/09
表7-15值均依照GC_TX_OFFS (寄存器 0x16, RF_CTRL_0)状态设置而定,该状态参数详见表
7-16。
北美对应表适用于最低电源电流。符合较宽泛的 IEEE802.15.4 标准的频谱旁瓣要求。
欧盟 1 和欧盟 2 对应表考虑到线性须保持频段外杂散发射在 ETSI 要求以下。
对应欧盟 1 使用的电源电流高于北美对应,并使用正态(线性化)PA 模式以便将 O-QPSK
100/200/400kbit/s 模式的介质输出功率提高到-1dBm,并将 BPSK 20kbit/s 模式的介质输出功率提
高到 2dBm。
对应欧盟 2 使用加速模式以提高电源电流为代价提高 TX 功率电平。因此,100/200/400kbit/s 的
O-QPSK 的 TX 功率最大值为 3dBm,20kbit/s 的 BPSK 的 TX 功率最大值为 5dBm。

按照中华人民共和国无线电管理局对低功率(短波)无线电设备的技术要求规定,中国映射表所
含频谱旁瓣必须保持< -36 dBm。
