摘　　要：为了满足5G大环境下的低功耗物联网节点应用,设计了一种新型谐波抑制负载结构的整流电路,在二极管后引入连续多阶微带谐波抑制结构,从而实现较高的转换效率和较小的输出纹波。该电路结构紧凑、设计成本低、结构简单,当输入功率为14.8 dBm时,电路的转换率可达72.5%。最后选择F 4 B基板进行实验验证,结果表明当负载为750Ω时,该电路结构的最高转换效率仍可以达到61.2%,相比于其他结构有明显的提高。In order to meet the low-power IoT node application in the 5G environment,this paper proposes a new type of harmonic suppression load structure in rectifier circuit,which introduces a continuous multi-order microstrip harmonic suppression structure behind the diode to achieve higher conversion efficiency and lower output ripple.The compact circuit has low design cost and simple structure.When the input power is14.8 dBm,the conversion efficiency can reach 72.5%.Finally,the F 4 B substrate is selected for experimental verification.The results show that when the load is 750Ω,the highest conversion efficiency of the circuit can still reach 61.2%,which is significantly improved compared to other structures.
