Para maximizar la transmisión de potencia a la línea laimpedancia de entrada de la línea debe serZin=Zg*.

Para conseguir esta impedancia de entrada proceda como se leindica en los apartados c) y d).

Determine:

c) La mínima longitud de la línea (en longitudes de onda) paraque la parte real de su admitancia de entrada sea 8×10-3Ω-1. Determine el valor de dicha admitancia de entrada.(10 puntos)

Si no ha resuelto el apartado (a) tomeZ0=50Ω.

d) La admitancia Y que debe colocarse en paralelo a la entradade la línea para que el generador vea una impedancia de entrada ala línea igual al conjugado de su resistencia interna. Verifiqueque efectivamente ahora Zin=Zg*. (5puntos)

Si no ha resuelto el apartado (b) tomeYin=0.008+j0.016 Ω-1.

e) La potencia media entregada a la carga en las condiciones delapartado (d). (3 puntos)

To maximize power transmission to the line the lineinput impedance must be Zin = Zg *.

To achieve this input impedance proceed as indicated insections c) and d).

Determine:

c) The minimum length of the line (in wavelengths) sothat the real part of its input admittance is 8 × 10-3 Ω-1.Determine the value of that input admittance. (10points)

If you have not solved section (a) take Z0 =50Ω.

d) The admittance Y that must be placed in parallel tothe input of the line so that the generator sees an input impedanceto the line equal to the conjugate of its internal resistance.Verify that effectively Zin = Zg * now. (5 points)

If you have not solved section (b) take Yin = 0.008 +j0.016 Ω-1.

e) The average power delivered to the load under theconditions of section (d). (3 points)
