Abstract :
The gain-frequency performance of the cascaded single-stage distributed amplifier (CSSDA) configuration, which was designed for power application, is considerably improved in terms of significantly reduced in-band gain ripple without compromising its bandwidth. This is achieved with the incorporation of passive components within artificial transmission lines constituting the CSSDA so that it exhibits frequency-dependent loss behaviour.
