设计了一种超宽带PHEMT单片倍频器。它包括一个FET有源巴伦级和一个共源极结构的推挽式倍频器。由于纯粹的集总元件概念，所需的芯片面积非常低。使用宽带补偿和匹配网络，在电路仿真中预测了接近平坦的输出功率性能，最高可达2/3 f/sub T/，且转换损耗可接受，并通过宽带波形测量得到证实。整个电路的稳定性进行了研究，包括隐藏的不稳定性和任意的被动输入和输出负载条件的基础上直接稳定圆计算。
An ultra-broadband PHEMT MMIC frequency doubler is designed. It comprises a FET active balun stage and a push-pull doubler in common-source configuration. Due to the purely lumped-element concept, the required chip area is very low. Using broadband compensation and matching networks, a nearly flat output power performance up to a limit of 2/3 f/sub T/ with acceptable conversion loss is predicted in circuit simulations and confirmed with broadband waveform measurements. The stability of the entire circuit is investigated including hidden instabilities and arbitrary passive input and output load conditions based on a direct stability circle calculation.
