A MMIC matrix amplifier design based on FETs with tapered gate width is proposed. The Tschebyscheff filter theory is applied to each of the artificial transmission lines composing the matrix amplifier. The improvement of the input and output reflection coefficient and the reduction of the FET's width in comparison to a conventional matrix amplifier with equivalent performance demonstrates the effectiveness of the presented approach.
