Answer to Question #153748 in Electric Circuits for Viccy

Question

ZL = 200 Ω and it is desired that Zi = 50 Ω The quarter wave transformer should have a characteristic impedance of

A. 100 Ω

B. 40 Ω

C. 10000 Ω

D. 4 Ω

Answer 1

Solution:

$Z_O= \sqrt{\smash[b]{Z_I\cdot Z_L}}= \sqrt{\smash[b]{200\cdot50}}=100$

$Z_L=Load \;impidence$

$Z_I=Input\;impidence$

$Z_O=Characteristic \;impidece$

Answer:

$Characteristic \;impidece\;is\;100\Omega$
