A millimeter wave amplifier constructed on a substrate and configured for use at a frequency of 75 GHz or higher, may include four amplifier stages. A first inter-stage filter, resonant at an operating frequency of the amplifier, may couple the output of the first stage to the input of the second stage. A second inter-stage filter, resonant at the operating frequency, may couple the output of the second stage to the input of the third stage. A third inter-stage filter, resonant at the operating frequency, may couple the output of the third stage to the input of the fourth stage. A plurality of bias supply leads that couple a gate bias voltage and a drain bias voltage to each of the amplifier stages. A plurality of bias line filters, resonant at the operating frequency, may be connected from at least some of the bias supply leads to a ground plane.
