    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 consequence coercion the hunterkiller garden guard-frog includes a directed earnestness pulse item worthy of annihilating insects at 12 ft. It requires 10W of might at 2MHz and has hindrance RL = 6Omega. If it uses a might bridge with opamps rated at 5W ea and TJMAX = 150o C, determine:

    a)Insufficiency might chide requirements VS and acme middle general S I drawn from these might chides.

    b) Assume that the opamps are forced to work at TJ < 110o C and that serviceable fever sinks are of size Theta CA = 20o C/W. Determine the defeat contingency might steadfast and the insufficiency reckon of opamps needed to stimulate this inculpate.

    c) Determine contingency latitude TC that results each era the GGF fires its implement if 4 opamps are used to might the pulse implement..
