Distributed power amplifier

A distributed amplifier having an input terminal and an output terminal comprising:

• a first plurality of successively coupled transistors, each one thereof having an input electrode and an output electrode;
• first means, including a first plurality of capacitors, for capacitively coupling each one of said input electrodes of the first plurality of transistors to the input terminal;
• a second plurality of successively coupled transistors, each one thereof having an input electrode and an output electrode;
• second means, including a second plurality of capacitors, for capacitively coupling each of said input electrodes of the second plurality of transistors to the input terminal;
• and
• a common means for electrically interconnecting the output electrode of each one of said transistors to the output terminal.

A distributed amplifier having an input terminal and an output terminal comprising:

• a first plurality of successively coupled field effect transistors with cascaded gate electrodes, cascaded drain electrodes, a first one of such field effect transistors having the gate electrode thereof coupled to the input terminal, such terminal being adapted to receive an input radio frequency signal, and the last one of the successively coupled field effect transistors having the drain electrode thereof coupled to an output terminal, said output terminal being adapted to provide an amplified output radio frequency signal;
• first means, coupled to each one of the gate electrodes of the first plurality of field effect transistors, for providing separate bias and radio frequency signal paths;
• a second like plurality of successively coupled field effect transistors with cascaded gate electrodes, cascaded drain electrodes, a first one of such field effect transistors having the gate electrode thereof coupled to the input terminal and the last one of the successively coupled field effect transistors having the drain electrode thereof coupled to the output terminal;
• second means, coupled to each one of the gate electrodes of the second plurality of field effect transistors, for providing separate bias and radio frequency signal paths;
• and
• common means, for electrically interconnecting the drain electrode of each one of the field effect transistors to the output terminal of the distributed amplifier.
