<p>A reduced loss coupling technique for combining multiple, parallel, gain-stages (101 - 10N) to form an amplifier. A first transmission line (8), with multiple taps, couples the inputs of the gain-stages together and to an input port (IN) for the amplifier. A second transmission line (9), also with multiple taps, couples the outputs of the gain-stages together and to an output port (OUT) for the amplifier. Preferably, the output port is connected to the end of the second transmission line while the input port is connected asymmetrically (off center) along the first transmission line. The actual position of the input port along the first transmission line is determined by the desired amount of phase mismatch of between signal paths through all of the gain-stages as measured from the input port to the output port. <IMAGE></p> |
