T-Attenuator

A T-attenuator is required to be inserted between an amplifier and a transmission line. The power level to the line is required to be restricted to -3 dB. The gain of the amplifier is fixed at 24 dB and its maximum input signal is at a level of -10 dB.

Sketch a block diagram of the arrangement and calculate suitable values of pad resistance if both the amplifier and the line have a characteristic impedance of 600 Ohm.

Please show as much working as possible and comment where possible.
