A quarter wave transformer matches a 100 ohm load to a transmission

Home » Electromagnetic Theory » Electromagnetic theory miscellaneous » Question

A quarter wave transformer matches a 100 ohm load to a transmission line with L = 1.35 µH/m and C = 60 pFm. The characteristic impedance of matching transformer is—

1. 150 Ω
2. 122.5 Ω
3. 275 Ω
4. 300 Ω

Correct Option: B

z² _λ/4 = z_in z_L ⇒ z_λ/4 = √z₀z₁

z_in =	√	L	= 150 Ω
