2.102. A series of microwave repeater links operating at 10 GHz are used to relay television sig- nals into a valley that is surrounded by steep mountain ranges. Each repeater consists of a receiver, transmitter, antennas, and associated equipment. The transmitting and receiving antennas are identical horns, each having gain over isotropic of 15 dB. The repeaters are separated in distance by 10 km. For acceptable signal-to-noise ratio, the power received at each repeater must be greater than 10 nW. Loss due to polarization mismatch is not expected to exceed 3 dB. Assume matched loads and free-space propagation conditions. Determine the minimum transmitter power that should be used.
Suppose a manufacturing error occurred and the oven was made 6.0 cm longer than specified in part (a). In this case, what would have to be the frequency of the microwaves for there still to be five antinodal planes of the electric field along the width of the oven?
a.What is the attenuation of 350 ft of RG-11 U coaxial cable at 100 MHz?b. A transmitter has an output power of 3 W that is fed to an antenna through an RG58A/U cable 20 ft long.

Two engineers have a disagreement over the selection of transmission line for connections within a 100m Data Centre on a project that is at risk for cost overrun. The first engineer is arguing in favor of using multi-mode fibre while the second engineer would like to use single mode fibre. You are the project engineer. Decide which of the two transmission lines to use and justify your answer.d. For typical silica optical fibres with ncore = 1.45 and Δ = 5 x 10-3, calculate nclad and NAe.

Ope X. The frequency spectrum of an AM signal is shown below: 5.5V 1V 1V 52kHz 58kHz a) if the modulating signal is a sine wave, write the equation of the modulating signal b) if the carrier signal is a cosine wave, write the equation of the carrier signal c) calculate the current of the AM signal flowing through a 300-ohm load
Question 3 a) For a single-frequency sine wave modulating signal of 3 kHz with a carrier frequency of 36 MHz, what is the spacing between sidebands? b) A carrier of 49 MHz is frequency-modulated by a 1.5-kHz square wave. The modulation index is 0.25. Sketch the spectrum of the resulting signal. (Assume only harmonics less than the sixth are passed by the system.)
Modify this circuit to extend the upper frequency limit to greater than 15 MHz. You may change the topology (i.e. configuration), but not the power supply voltage or collector bias current. The circuit voltage gain must be 46dB +/- 1 dB. Provide simulation results to show AC frequency responses of both circuits on the same plot, and annotate the 3dB upper frequency limit on both traces. Use typical ẞ values from the data sheet for the simulation. You may assume that 1% resistors are available in values below 100. The circuit must adhere to Standard Bias techniques.
