Design a ∏ section symmetrical attenuator to provide a voltage attenuation of 15 dB and a characteristic impedance of 600 Ω.
Z_{S} = Z_{L} = Z
R_{1} = R_{3} = Z (K + 1 / K 1)
R_{2} = Z (K^{2}  1 / 2 K)
Z = 600Ω
K = 15dB = 15^{(15/20)} = 5.6234
R1 = R3 = 600 (5.6234 + 1 / 5.6234  1)
= 859.54 Ω
R2 = 600 (5.6234^{2}  1 / 2 x 5.6234)
= 600 (30.6226 / 11.2468)
= 1633.67 Ω
Can someone please confirm if I am on the right lines? Thanks
Homework Statement
Design a ∏ section symmetrical attenuator to provide a voltage attenuation of 15 dB and a characteristic impedance of 600 Ω.
Homework Equations
Z_{S} = Z_{L} = Z
R_{1} = R_{3} = Z (K + 1 / K 1)
R_{2} = Z (K^{2}  1 / 2 K)
The Attempt at a Solution
Z = 600Ω
K = 15dB = 15^{(15/20)} = 5.6234
R1 = R3 = 600 (5.6234 + 1 / 5.6234  1)
= 859.54 Ω
R2 = 600 (5.6234^{2}  1 / 2 x 5.6234)
= 600 (30.6226 / 11.2468)
= 1633.67 Ω
