The output stage of an RF front end consists of an amplifier followed by a filter and then an antenna. The amplifier has a gain of 27  dB, the filter has a loss of 1.9  dB, and of the power input to the antenna, 45 % is lost as heat due to resistive losses. If the power input to the amplifier is 30 dBm, calculate the following: (a) What is the power input to the amplifier? (b) Express the loss of the antenna in decibels. (c) What is the total gain of the RF front end (amplifier filter)? (d) Wh
