微波系统的设计者经常处于困境,不得不使他的创造性仅限于反映现有可用微波器件的水平。显然,获得现有器件的功率、频率和频宽等方面的技术发展状况决定了整个系统所能达到的性能。用于此领域的器件通常不再是实验室的珍品,提交成批生产之前,必须对这些器件进行试验和分析,以确定其再生产的能力、成本和可靠性。此外,在系统定型之前就必须确定基本的设计原则:是采用固体器件还是采用电子 Designers of microwave systems are often in a dilemma and have had to limit their creativity to only reflecting the level of available microwave devices. Clearly, the state-of-the-art in terms of power, frequency, and bandwidth for existing devices dictates the performance of the overall system. Devices used in this area are generally no longer treasures in the laboratory and must be tested and analyzed before being submitted for mass production to determine their ability, cost, and reliability to reproduce. In addition, basic system design principles must be defined prior to system prototyping: solid-state devices or electronic
