Abstract
A millimeter wave power amplifier is disclosed. In an exemplary embodiment, a MM wave power amplifier (PA) includes a plurality of amplifier stages coupled together to receive a MM wave input signal and produce an amplified MM wave output signal, and one or more feedback elements coupled across the amplifier stages, each feedback element coupled across an odd number of the amplifier stages to increase an operating bandwidth of the PA.
