【选型】单结表面贴装环形器DP0243C/DP0244C/DP0283C/DP0284C，助力5G小基站功放设计
5G小基站主要用于室内覆盖，平均输出功率一般有0.1W、0.25W 和0.5W三种功率等级。针对输出功率达到0.5W的5G小基站，末级PA输出端需要增加环形器，可以提高收发隔离度，防止发射信号影响接收通道性能。
针对国内主流的5G通信频段2.6GHz和3.5GHz的小基站设备，大普通信推出了小尺寸、表贴封装的环形器DP0243C/DP0244C/DP0283C/DP0284C，工作频段覆盖2496-2690MHz和3300-3600MHz，最大插入损耗0.35dB，隔离度可以达到21dB，尺寸是圆型直径7mm，以下是DP0243C/DP0244C/DP0283C/DP0284C环形器电气参数：
环形器用于末级功放输出端，要求损耗尽量低，大普的DP0243C/DP0244C系列环形器的插损小于0.35dB，DP0283C/DP0284C系列环形器插损小于0.25dB，可以提高末级PA的工作效率，降低小基站功耗；
环形器的作用是增加收发隔离，DP0243C/DP0244C/DP0283C/DP0284C环形器反向隔离度达到21dB，可以降低发射信号对接收端电路的影响，提高设备的可靠性；
5G小基站平均发射功率一般都小于0.5W，峰值功率也在10W以内，大普环形器15W以上的额定功率足以满足应用需求；
5G小基站对小型化要求较高，DP0243C/DP0244C/DP0283C/DP0284C环形器只有7mm直径的封装，减小内部占用空间和降低整机重量，利于5G小基站的轻量化设计，同时可以贴片焊接，降低生产成本。
图 DP0243C/DP0244C/DP0283C/DP0284C环形器典型封装尺寸
综上所述，大普的环形器DP0243C/DP0244C/DP0283C/DP0284C具有7mm直径小尺寸封装、21dB隔离度，覆盖5G主流频段、贴片封装的特性，同时相比国外同类产品，成本更低，是5G小基站环形器的优秀选择。
