Title
Initial Evaluation of an Evolvable Microwave Circuit
Abstract
Microwave circuits are indispensable for mobile and multi-media communication. However, these circuits are very difficult to design, because of the nature of distributed-constant circuits in the microwave range (i.e., over 1 GHz). These circuits are also difficult to adjust for optimum performance, even for experienced engineers. These related problems make development costs of microwave circuits very high. In order to overcome these problems, we propose an EHW-based microwave circuit where performance adjustment is carried out automatically by a GA. This new approach of integrating a performance adjustment function within the circuit eliminates many of the design problems with associated these circuits. In this paper, we present an EHW-based image-rejection mixer circuit, which we have developed with this approach, and experimental data that demonstrates that the automatically adjusting circuit is capable of outperforming a circuit adjusted by an experienced engineer.
