开发了一种基于 GaAs 上 0.15-/spl mu/m pHEMT 的共面再生分频器单片微波集成电路 (MMIC)，用于 94/47-GHz 频率转换，实现了 23% 的稳定分频带宽。在 -2 dBm 的输入电平和 8 mW 的直流功耗下，无需使用额外的缓冲放大器，即可获得 2.5 dB 的极低转换损耗。工作频率可通过反馈网络中的变容二极管在 2.5 GHz 范围内进行调节，以补偿技术变化。提出了使用有源和无源元件的精确建模来模拟稳定和不稳定操作以及带宽和转换性能的各种方法。
A coplanar regenerative frequency divider monolithic microwave integrated circuit (MMIC) based on 0.15-/spl mu/m pHEMTs on GaAs for 94/47-GHz frequency conversion has been developed, achieving a bandwidth of 23% for stable division. A very low conversion loss of 2.5 dB was obtained with an input level of -2 dBm and a dc power consumption of 8 mW, without using additional buffer amplifiers. The frequency of operation can be tuned by a varactor diode in the feedback network over a 2.5-GHz range to compensate for technology variations. Various methods for the simulation of stable and unstable operation and bandwidth and conversion performance are presented, using accurate modeling of the active and passive components.
