Abstract :
A novel phase conjugator for retrodirective array has been developed. Each element employs a balanced FET mixer, which provides effective isolation between RF and IF signals with identical frequencies to realize phase conjugation. Taking advantage of FETs, a compact circuit has been designed, which allows the array spacing to be small, while the performance was comparable.
