Abstract
A two dimensional distributed amplifier phase shifter having a distributed reference amplifier circuit generating a reference signal, the reference amplifier circuit having its input connected to one end of a plurality of serially connected microstrip transmission lines. The phase shifter further has a plurality of phase shifted amplifier circuits, one associated with each of the microstrip transmission lines. Each phase shifted amplifier circuit has an input connected to an end of its associated microstrip transmission line which is opposite the reference amplifier circuit and generates an output signal, phase shifted from the reference signal or the output signal of an adjacent phase shifted amplifier by a predetermined phase angle. The phase shifter may be fabricated as a monolithic microwave integrated circuit.
