Abstract :
The relationship between microwave power absorbed by a detector diode and the resulting detected voltage at high signal level is investigated. Experimental data is obtained from a zero biased diode mounted in a rectangular waveguide system operating at 9.5 GHz. The Alpa Industries Inc. 4561, 6724 and 6725 Schottky diodes and the MA-COM 1N23 point contact diode with 1 kΩ and 106 kΩ loads are examined. The P-V relationships are analyzed by solving a system of nonlinear differential equations based on a lumped parameter model of the microwave system and diode
