4. Consider a transmitter with a power output of $130\mathrm{W}$. Please provide its power output in $\mathrm{dBW}$ and $\mathrm{dBm}$. Assuming a communication channel with a $130\mathrm{W}$ transmitted power, a transmitter antenna gain of $58\mathrm{dBi}$, and a receiver antenna gain of $15\mathrm{dBi}$, calculate the path loss and received power for a distance of $30\mathrm{km}$ and a frequency of $6\mathrm{GHz}$. Express the received power in $\mathrm{dBm}$ and milliwatts. 5. If the distance between the antennas is increased from $30\mathrm{km}$ to $60\mathrm{km}$ while maintaining the same received power, determine the new required operating frequency. Analyze a system of three cascaded amplifiers, as illustrated in slide 42 . Calculate the system's equivalent noise temperature (Te) given the following gains and noise temperatures: G1 = 10 $\mathrm{dB},\mathrm{G}2=16\mathrm{dB},\mathrm{G}3=12\mathrm{dB};$ Te1 $=2000\mathrm{K}$, Te2 $=1050\mathrm{K},\mathrm{Te}3=4000\mathrm{K}$. Determine the output noise temperature (Tout) and equivalent noise temperature (Te) for the system. Evaluate the impact of swapping the positions of amplifiers G2 and G3. What conclusion can be drawn from this analysis?
