What is value of guarantee a maximum dissipated power

Question

Assignment:

1. Calculate the following:

a) (P1)mW = 0.10 mW in dBm.

b) (P2)dBm = 40 dBm in W.

c) (P3)dBm = -30 dBm in dBrn.

d) (P4)dBm = -40 dBm in dBW.

e) (P5)pW = 30 pW in dBrn.

2. Let a matched two-terminal device have open circuit source voltage v_i(t) = A[1 + cos(2πƒ_ct)] cos(2πƒ₀t) with f0 = 10 fc. Let the device be closed on a resistive load RL = 100. What is the value of A in order to guarantee a maximum dissipated power at the load (P_max)_dBm = 5 dBm?
