【选型】表面贴装射频负载SMT252503ALN2F应用于大功率5G通信基站,可耐受150W的射频功率
为保证覆盖范围,室外大功率的5G小基站峰值发射功率高达150w,甚至更高,对收发信道的每一器件要求的更高,设计上要求也更加严格,保证产品可靠性。在接收通道设计中,往往会增加功率负载,来确保故障情况下,接收支路免受损坏。EMC-RFLABS公司推出的表面贴装射频负载SMT252503ALN2F具备功率大、体积小的特点,能够满足大功率5G小基站的严苛要求。
如下图所示,是SMT252503ALN2F在5G小基站在射频链路的位置。其主要功能是发射时,接收通道开关连通环形器与功率负载,这样功率负载就能吸收发射功放泄露到接收通道的功率信号,不至于大功率信号传输到接收链路,致其损坏。
其对功率负载的要求很简单:耐功率要达到泄露功率的最大值,优秀的驻波参数,小体积。
1、 SMT252503ALN2F具有最高150W的平均耐受功率,能够满足绝大多数小站发射功放的全功率输入。
2、 其驻波参数非常优秀,DC~2.7GHz时,VSWR<1.13;2.7~4GHz时,VSWR<1.20,这样SMT252503ALN2F的反射功率就非常小,反射功率不会损坏其他物件。
3、 小体积,5G小基站设计,“寸土寸金”对尺寸的容忍度有限,SMT252503ALN2F采用表贴方式,占用PCB空间约6.5x6.5mm,其封装外形如下图所示:
4、 适用温度高,5G小基站小体积、高热量,自然散热能力有限,机体温度必然很高,对各元器件的温度耐受程度有比较高的要求,SMT252503ALN2F能够在-55℃~+150℃正常工作,可以保证产品不会再功率负载上有短板。
综上,SMT252503ALN2F能够耐受150W的射频功率,耐受最高温度达150℃,有非常小的驻波参数,能够保证5G小基站的性能和可靠性,是基站RRU设计中不错的选择。
