92 GHz～96 GHz双通道上变频关键技术研究
Research on key technologies of dual-channel up-conversion in the 92 GHz～96 GHz
摘要
Abstract
To achieve the miniaturization design of the W-band frequency conversion module,the paper presents a dual-channel up-conversion module with an output frequency ranging from 92 GHz to 96 GHz.The module takes two independent intermediate frequency(IF)signals ranging from 8 GHz to 12 GHz as inputs for each channel and uses a common 14 GHz local oscillator(LO)signal.The 14 GHz LO signal is divided into two parts and then enters a sextupler to mix with the IF signals,generating radio frequency(RF)signals between 92 GHz and 96 GHz.The functionality of the up-conversion module is ultimately achieved through the selection of critical components and the design of passive devices,including W-band finlines,an 84 GHz high-suppression LO filter,and a 92 GHz～96 GHz high-suppression RF filter.The layout of the entire module positions both the input and output ports along its length,with an integrated module size of 121 mm ×38.2mm × 19.1 mm(excluding SMA connectors).Test results reveal that a linear output within the 92 GHz～96 GHz frequency band is achieved within a high dynamic input range of-100 dBm to 0 dBm for the IF signals,with a small-signal gain of approximately 5 dB and an 84 GHz LO signal leakage of less than-110 dBm.The up-conversion module designed in this paper possesses practical application value and provides a reference for the design of miniaturized and integrated up-conversion modules with high dynamic range and high suppression.关键词
