Abstract
A novel frequency tunable bi-directional phased array processing consisting of variable phase shifting and amplitude adjustment which employs a vector modulator and active combiner and splitter is proposed. Advantages of the proposed bi-directional a phased array processing includes the following 1) compact size; 2) high efficiency; 3) reduced passive trace loss and power consumption; 4) active current combining; 5) high input-output isolation; 6) high resolution and precise gain control and unequal combining or splitting; 7) phase-invariant amplifier design; 8) high accuracy and high-resolution phase shifter; 9) frequency tunability, within a small frequency range and/or a large frequency range; and 10) optimal unequal combining or splitting.
