2. The output stage of a transmitter requires, owing to supply voltage limitations, a downward impedance transformation of the antenna resistance. The load impedance is 50-Ω. Suppose we wish to deliver 3 Watts of power into such a load at 915 MHz, but the power amplifier has a maximum peak-to-peak sinusoidal voltage of only 7 Volts because of various losses and transistor breakdown problems. Design a two section L-match of low pass type to allow that 3 Watts to be delivered to the 50-Ω load. Assume that all reactive elements are ideal.
