| Abstract | ||
| In this paper, an integrated Traveling-Wave Amplifier (TWA) using Monolithic Microwave Integrated Circuit (MMIC) technology is proposed and carefully implemented. The classical structure of the five-stage amplifier is modified depending on the matrix form instead of the cascaded form with just one cell at each row of the matrix. This modification is shown to render the amplifier suitable for very large Gain-Bandwidth Product (GBP) operation in small on-chip area. Microwave office program simulation of the proposed design shows that it has excellent performance as compared to the conventional amplifiers with smaller area. The forward gain is 30dB with ±1dB flatness and 3dB bandwidth of about 30 GHz, which is the best results reported till now. The TWA is suitable for Digital Video Broadcasting (DVB) and satellite applications. Keyword: Microelectronics, Traveling wave amplifier, MMIC. | ||
