Abstract
In a cascode distributed amplifier of the present invention, a plurality of unit circuits are connected in parallel, and each unit circuit includes a pair of first and second transistors connected in series between an input transmission wire and an output transmission wire. The first transistor has a gate connected to the input transmission wire, a source grounded and a drain connected to the second transistor. The second transistor has a gate grounded, a source connected to the drain of the first transistor and a drain connected to the output transmission wire. Each unit circuit includes a damping resistor having a first end connected to the gate of the second transistor and a second end, and a capacitor having a first end connected to the second end of the damping resistor and a second end grounded.
