A single-pole, single-throw switch is constructed using two identical PIN diodes in the arrangement shown below. In the ON state, the series diode is forward biased and the shunt diode is reversed biased; and vice versa for the OFF state. If $f=6 \mathrm{GHz}, Z_0=50 \Omega, C_f=0.1 \mathrm{pF}, R_r=0.5 \Omega, R_f=0.3 \Omega$, and $L_i=0.4 \mathrm{nH}$, determine the insertion losses for the ON and OFF states.
