Abstract
A broadband high power amplifier architecture is disclosed. One example configuration includes a first plurality of distributed amplification cells connected in a first string, wherein a conductive trace operatively coupling outputs of the first string cells is a stepped structure, such that the associated inductance successively decreases from a first cell to a last cell of the first string. The amplifier further includes a second plurality of distributed amplification cells connected in a second string, wherein a conductive trace operatively coupling outputs of the second string cells is a stepped structure, such that the associated inductance successively decreases from a first cell to a last cell of the second string. A combiner combines output signals of the first and second strings. Additional strings and/or stages can be provided, and the degree of combining will depend, for example, on factors such as the application and desired output power.
