A novel phase conjugator for retrodirective array applications is presented in this paper. Such conjugator provides good operation, in terms of conversion efficiency, with no need of DC biasing. That is made possible thanks to the use of E-PHEMT transistors, whose characteristics are exploited in order to obtain a resistive mixing function in the desired VGS = VDS = 0V point. The proposed solution is validated through the successful implementation of a four element retrodirective array.
