    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..

    Expert Answer

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

    a)Incompleteness authority chide requirements VS and apex mediocre floating S I drawn from these authority chides.

    b) Assume that the opamps are obdurate to effect at TJ < 110o C and that helpful excitement sinks are of size Theta CA = 20o C/W. Determine the vanquish plight authority firm and the incompleteness number of opamps needed to push this attack.

    c) Determine plight weather TC that results each space the GGF fires its instrument if 4 opamps are used to authority the pulse instrument..
