An amplifier uses a transistor that has the following S-parameters at an operational frequency of 5.4 GHz (Z0=50?): S11=0.61exp(-j1700), S12=0.06exp(j700), S21=2.3exp(j800), and S22=0.72exp(-j250). The input of the amplifier is connected to a source with Vs=2V (peak) and ZS=25?; the output is connected to a load of ZL=100?.
a) What are the input and output impedances of the transistor? Please report your answer in real and imaginary parts.
b) Find the operating power gain, the available gain, the transducer gain, and the unilateral transducer gain, all in dB.
c) Compute the available power from the source and the power delivered to the load in dBm.
