Abstract : The problem of wide bandwidth and flat in-band gain response for microwave transistor amplifiers has been reduced to the optimization of a number of important variables from computer-prepared design charts. Through the general flexibility of the computer-generated data, a large variety of amplifier responses are possible using distributed circuit matching networks. The work of H. A. Wheeler is presented in order to accomplish the transition for the TEM (transverse electromagnetic) solution obtained for transistor response to the microwave integrated circuit technology (microstrip). As experimental verification of the overall design procedure, single-stage and two-stage octave wide transistor amplifiers were fabricated on 1 inch by 1 inch and 1 inch by 1/2 inch 20-mil-thick alumina, respectively. The experimental data gained from these units showed excellent correlation to the computer-predicted response. (Author)
