A proposed design for the broadband microwave distributed amplifiers

الملخص EN

In this paper, a new method for the design of the broadband RF/microwave amplifiers employing distributed amplification is presented.

It proposes to use stages with asymmetric lumped elements (inductances and capacitances) in the gate and drain circuits of the amplifier instead of symmetric elements in order to control the frequency response and to achieve a flat gain over a large bandwidth.

The need for impedance matching problems is also solved.

Simulation result obtained demonstrates that the new design gives better frequency response as compared to the conventional distributed amplifiers even without optimization.
