Patent ID: 7804357

Claim:
A distributed amplifier comprising: an input side transmission line; an output side transmission line; plural push-pull amplifier circuits connected to said input side transmission line and said output side transmission line; and a constant-voltage power source capable of supplying a constant voltage; wherein each of said plural push-pull amplifier circuits has a push side transistor that is a field-effect transistor having a source, a drain and a gate and a pull side transistor that is a field-effect transistor having a source, a drain and a gate, said input side transmission line is directly connected to the gates of said push side transistor and said pull side transistor, said output side transmission line is directly connected to the source of said pull side transistor and to the drain of said push side transistor, said constant-voltage power source is directly connected to the drain of said pull side transistor, the source of said push side transistor is grounded, and wherein the plural push-pull amplifier circuits are not part of the output side transmission line.
