低成本、308MHz、315MHz和433.92MHz FSK收发器，带有N分频PLL

MAX7031是基于晶振的分数N分频收发器，设计用于发送和接收工厂预设的载波频率为308MHz、315MHz和433.92MHz的FSK数据，数据速率高达33kbps (曼切斯特编码)或66kbps (NRZ编码)。该器件可为50Ω负载提供+10dBm的典型输出功率，典型灵敏度为-110dBm。MAX7031具有独立的发送和接收引脚(PAOUT和LNAIN)，提供内部RF开关，用于发送和接收引脚与共用天线的连接。\nMAX7031的发送频率由一个16位、分数N分频、锁相环(PLL)产生，接收器本振(LO)由整数N分频PLL产生。由于分数N分频PLL被预设在高于接收LO 10.7MHz，所以这种 ·单电源供电：+2.1V至+3.6V或+4.5V至+5.5V \n·单晶体收发器\n·工厂预设频率(无需串行接口) \n·FSK调制 \n·工厂预设FSK频偏 \n·为50Ω负载提供+10dBm输出功率\n·内置TX/RX开关\n·内置发送和接收PLL、VCO和环路滤波器\n·镜频抑制> 45dB\n·典型RF灵敏度*：-110dBm \n·可由外部滤波器选择IF带宽 \n·具有高动态范围的RSSI输出 \n·发送模式下电流< 12.5mA\n·接收模式下电流< 6.7mA\n·关断电流< 800nA\n·快速上电启动, 启动时间< 250µs \n·小尺寸32引脚、薄型QFN封装;
