Unformatted text preview: P rd P edition, 1994). 1. Review Problem Consider a parallel-plate transmission line made of perfectly conducting plates. The plates are 1 mm wide and are spaced by 50 µ m. The plates are separated by an insulator with relative dielectric constant ε r = 9. Assume µ = µ o . The transmission line has characteristic impedance o Z 6.3 Ω ± . Assume the transmission line is driven at one end by a sinusoidal voltage source. At the other end a load resistor R = 25 Ω is connected. The transmission line is 10 cm long. For what range of frequencies (work out approximate numbers!) can the transmission-line and resistor combination be modeled as a (frequency-independent) lumped circuit equivalent? Draw the equivalent circuit for this frequency range, and explain your answer. 2 2) 8.2b 3) 8.3b 4) 8.4a 5) 8.4c 6) 8.5a 7) 8.5f...
