摘要
A compact Ka-band monolithic microwave integrated circuit(MMIC) voltage controlled oscillator (VCO) with wide tuning range and high output power,which is based on GaAs PHEMT process,is presented.A method is introduced to reduce the chip size and to increase the bandwidth of operation.The procedure to design a MMIC VCO is also described here.The measured oscillating frequency of the MMIC VCO is 36±1.2GHz and the output power is 10±1dBm.The fabricated MMIC chip size is 1.3mm×1.0mm.
设计并流片制作了基于GaAsPHEMT工艺的Ka波段微波单片集成压控振荡器(MMICVCO).该VCO具有紧凑、宽电调谐带宽及高输出功率的特点.提出了缩小芯片面积及增大调谐带宽的方法,同时还给出了设计MMICVCO的基本步骤.该方法设计并流片制做的MMICVCO的测量结果为:振荡频率为36±1.2GHz,输出功率为10±1dBm,芯片面积为1.3mm×1.0mm.
