摘要

In this work, the neural performance and fuzzy logic data sheets of the transistor are used to determine the feasible design target space in the optimization of a microwave amplifier. The compatible (Noise F, Input VSWR V_i, Gain G_T) triplets and their (Z_S, Z_L) terminations of a microwave transistor are exploited for an amplifier design with the minimum noise F_(min)(f), required gain G_(Treq)(f), and a low input VSWR V_i over the available bandwidth. The multi-objective design procedure is obtained from Z_S(f), Z_L(f) terminations with the unit-elements and short-circuited stubs in the L+L configurations and memetic optimization algorithm is successfully implemented as an optimization tool. A typical design example is given with its challenging performance in the simple L+L configurations realizable by the microstrip line technology.
