Abstract :
Results of a load impedance function that will present conditions for the simultaneous occurrence of maximum voltage and maximum power at the terminals of a linear transducer circuit are given. The statement is based on algebraic solution to the problem of capability limits in voltage- and resistance-constrained radial transmission lines. As a result, it is shown that the load impedance conditions for maximum power with conjugate matching and Brainerd´s maximum load voltage condition are embodied in the generalized load impedance function as the upper and lower limiting states of maximum received power; and that a purely resistive state for this function will determine the limit to stable power transfer. In addition, a case for the optimum transmission reactance that will enable extraction of maximum voltage at the maximum powers of conjugate impedance matching is demonstrated.
