摘　　要：文中主要研究衰减器在射频域的数值计算问题。通过运用转移参量A和散射参量S,对T型网络和Π型网络的电阻取值进行了理论研究,推导出了计算公式,进而计算了特征阻抗Zo为50Ω时T型网络和Π型网络电阻值,并用仿真软件验证了电阻取值的科学性和实用性。In this paper, we mainly consider the numerical computation problem of attenuator in the RF domain. By using transfer parameter A and scatter parameter S, a theoretical research has been done in resistance value of type T and type Πnetworks, and an induction on computation equation has been made. Then we calculate the resistance value of type T and typeΠ networks when characteristic impedance is 50 Ω, and use a simulation software to verify the reasonability and practicability.
