Phase conjugator for active retrodirective arrayapplications
Electronics Letters, 2000 A novel phase conjugator for active retrodirective array applications is presented. The circuit provides conversion gain as well as phase conjugating operation by using active devices, and results in a simple and compact design through the use of a common port for RF and IF signals.
