Abstract:
A distributed amplifier comprising:two or more unit FETs, each having a source electrode, a drain electrode, and a belt-shaped gate electrode arranged therebetween, the unit FETs being substantially linearly arranged in the length direction of the gate electrode on a substrate; each pair of neighboring source electrodes, neighboring drain electrodes, and neighboring gate electrodes being electrically connected to each other by a respective circuit in consecutive order of the two or more unit FETs; and an input portion connected to one end of the circuit which connects the gate electrodes, and an output portion connected to one end of the circuit which connects the drain electrodes, wherein an inductor or high-impedance transmission line is provided in either or both of the circuit which connects the neighboring drain electrodes and the circuit which connects the neighboring gate electrodes.
