Abstract :
In this paper a diode power detector circuit is investigated for application in a six-port communications receiver. The diode behavior is modeled by the fundamental diode equation, which is solved for the output DC operating point applying an expansion theorem of modified Bessel functions for the exponential function. The results are compared with a Harmonic Balance system simulation and the closely matching results show that the assumptions made to find the numerical solution hold true.
