MAX2900–MAX2904是完备的单片200mW发送器，专为868MHz/915MHz波段的应用而设计。MAX2900/MAX2901/MAX2902符合FCC CFR47的第15.247部分有关902MHz至928MHz ISM波段的规范。MAX2903/MAX2904符合为欧洲868MHz ISM波段设定的ETSI EN330-220规范。
这些发送IC在提供高度集成的同时大大减少了外部元件的数量，这一目标是通过完全集成的发送调制器、功率放大器、RF VCO、8通道频率合成器以及基带PN序列低通滤波器实现的。通过对BPSK调制信号滤波，降低了杂散信号的辐射，在美国ISM波段内能够获得八个独立的发送信道。为扩频BPSK、ASK和OOK提供输入，通过直接调制VCO实现调频(FM)。这些器件适合与外部差分天线配合使用。
