一、引言抗负载失配能力是衡量微波功率晶体管可靠性的重要指标之一,提高功率器件的抗负载失配能力,是器件研制中的一项重要任务。通过对器件抗负载失配能力进行实验和分析,可以为改进器件设计、调整工艺条件提供有用的参考数据。在实际应用时,负载局部失配,甚至全部失配的情况都是可能发生的。所以对功率器件来说,应该给出允许失配的范围和条
I. INTRODUCTION Anti-load mismatch capability is one of the important indexes to measure the reliability of microwave power transistors. It is an important task in device development to improve the anti-load mismatch ability of power devices. By experimenting and analyzing the mismatch capability of the device, it can provide useful reference data for improving the device design and adjusting the process conditions. In practical applications, the load partial mismatch, or even all mismatch situations are likely to happen. So for power devices, you should give the range and bars that allow mismatch
