SX1239IMLTRTRF/IF射频/中频RFID的射频接收器规格书PDF中文资料

SX1239IMLTRT属于RF/IF射频/中频RFID的射频接收器。由升特制造生产的SX1239IMLTRT射频接收器RF 接收器用于接收已调制的射频信号并对其进行解调，然后将数据传送到系统中进行处理。频率范围是 AM、FM、WB、0 Hz 至 64 GHz，数据速率为 250 bps 至 16 Gbps，数据接口包括连接器、I2C、I2S、引脚焊盘、并行、PCB、串行、焊盘、SPI、UART 和 USB。

GENERAL DESCRIPTION

The SX1239 is a highly integrated RF receiver capable of operation over a wide frequency range, including the 433, 868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands. Its highly integrated architecture allows for a minimum of external components whilst maintaining maximum design flexibility. All major RF communication parameters are programmable and most of them can be dynamically set. The SX1239 offers the unique advantage of programmable narrow-band and wide-band communication modes without the need to modify external components. The SX1239 is optimized for low power consumption while offering high sensitivity and channelized operation. TrueRF™ technology enables a lowcost external component count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations.
