    Standard equipment issue for the hunterkiller garden guard-frog includes a directed energy pulse unit capable of annihilating insects at 12 ft. It requires 10W of power at 2MHz and has resistance RL = 6Omega. If it uses a power bridge with opamps rated at 5W ea and TJMAX = 150o C, determine: a)Minimum power rail requirements VS and maximum average current S I drawn from these power rails. b) Assume that the opamps are constrained to operate at TJ < 110o C and that available heat sinks are of size Theta CA = 20o C/W. Determine the worst case power dissipated and the minimum number of opamps needed to drive this load. c) Determine case temperature TC that results each time the GGF fires its weapon if 4 opamps are used to power the pulse weapon..

    Standard equipment manifestation for the hunterkiller pasture guard-frog includes a directed energy pulse individual choice of annihilating insects at 12 ft. It requires 10W of susceptibility at 2MHz and has opposition RL = 6Omega. If it uses a susceptibility bridge with opamps rated at 5W ea and TJMAX = 150o C, determine:

    a)Reserve susceptibility chide requirements VS and acme medium present S I drawn from these susceptibility chides.

    b) Assume that the opamps are unyielding to act at TJ < 110o C and that helpful passion sinks are of size Theta CA = 20o C/W. Determine the batter plight susceptibility rapid and the reserve sum of opamps needed to incite this impute.

    c) Determine plight region TC that results each opportunity the GGF fires its utensil if 4 opamps are used to susceptibility the pulse utensil..
