I have a doubt on quater wave impedance tranformer. As i going thru a IEEE paper on inthis matter, i found out the the electrical length is defined in Θ, degree. assume given 90° for Θ=λ/4 length. How do we find the operting frequnecy of the circuit?
u have any document whr i can learn this..? what is λ or d=?
n=? i have gotten this information from
IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES, VOL. 52, NO. 12, DECEMBER 2004
A Broad-Band Quarter-Wavelength Impedance
Transformer With Three Reflection
Zeros Within Passband
Ok look... frequency is : f=v/λ
---------------------------------
v=velocity of el.mag. wave in material
λ=wavelenght in material...
--------------------------------
What information do you have ?
"it declares the Θ=90° to be 1Ghz"... it is immposlible to find frequency without additional info about wavelenght and characteristics of material.
