GATE EC 2017 Set 2 Q54 — Transmission Lines

Standard air-filled rectangular waveguides of dimensions $a=2.29$ cm and $b=1.02$ cm are designed for radar applications. It is desired that these waveguides operate only in the dominant $TE_{10}$ mode with the operating frequency at least $25 \%$ above the cutoff frequency of the $TE_{10}$ mode but not higher than $95 \%$ of the next higher cutoff frequency. The range of the allowable operating frequency $f$ is

A complex load (in $\Omega$ ) is represented as $\Gamma_{L}=0.5 \angle 30^{\circ}$ on the Smith chart. A co-axial cable with a characteristic impedance of $50 ~\Omega$ is connected to the load. The new input impedance of the load now moves to a diametrically opposite point on the same $\Gamma$ circle on the Smith chart. Which option is the nearest …

A $50 \Omega$ lossless transmission line is terminated with a load $\mathrm{Z}_{\mathrm{L}}$ of $(50-\mathrm{j} 75) \Omega$ . If the average incident power on the line is $10 \: \mathrm{mW}$ , then the average power delivered to the load (in $\mathrm{mW}$ , rounded off to one decimal place) is $\_\_\_\_\_\_\_$ .
