Distributed amplifiers with controllable linearization are provided herein. In certain embodiments, a distributed amplifier includes a differential input transmission line, a differential output transmission line, and a plurality of differential distributed amplifier stages connected between the differential input transmission line and the differential output transmission line at different points or nodes. The distributed amplifier further includes a differential non-linearity cancellation stage connected between the differential input transmission line and the differential output transmission line and providing signal inversion relative to the differential distributed amplifier stages. The differential non-linearity cancellation stage operates with a separately controllable bias from the differential distributed amplifier stages, thereby providing a mechanism to control the linearity of the distributed amplifier.
