【选型】小尺寸封装的带通滤波器SLFB18-2R450G-36TF用于Zigbee模组,插损<1.3dB
ZigBee模组主要用于智能家电、消费电子领域的无线通讯互联,具有低数据速率、低功耗的特点,核心器件是Zigbee无线收发芯片,为提高连接稳定性,降低通信干扰,需要外加带通滤波器。
针对Zigbee模组中接收电路滤波的应用,推荐顺络带通滤波器SLFB18-2R450G-36TF,采用LTCC工艺制造,工作频率2400-2500MHz,带内插入损耗1.3dB,带外抑制30dB@4800-5000MHz,0603小尺寸封装,以下是SLFB18-2R450G-36TF典型电气性能参数:
1、Zigbee模组工作在2400-2500MHz频段,与移动通信2.6GHz频段比较接近,容易收到干扰影响通讯质量,推荐采用顺络的带通滤波器SLFB18-2R450G-36TF,带内插入损耗小于1.3dB,带外抑制大于20dB,可以降低非工作频段对Zigbee信号的干扰,提高通讯距离和稳定性。
2、Zigbee模组用于智能家居和可穿戴产品,体积比较小,对内部器件尺寸要求较高,带通滤波器SLFB18-2R450G-36TF的封装尺寸是1.6*0.8*0.65mm,减少PCB占用面积,提高空间利用率。
3、带通滤波器SLFB18-2R450G-36TF可以提供卷带包装,利用SMT贴片便于批量生产,无外围匹配电路,降低BOM成本,以下是该器件推荐PCB版图。
