L频段异构集成射频收发前端设计与实现
Design and realization of L-band heterogeneous integrated RF transceiver front-end
摘要
Abstract
To meet the lightweight,miniaturized and multifunctional application requirements of RF systems below 2 GHz,a design of L-band heterogeneous integrated RF transceiver front-end microsystem with stacked architecture was proposed.Through system requirement analysis,multi-layer heterogeneous integration scheme planning,circuit design,and key transmission structure simulation verification,the overall architecture design of the microsystem was completed.Based on silicon-based micro-electro-mechanical systems(MEMS)technology and high-precision micro-assembly techniques,high-density heterogeneous integration of chips and devices with different materials,such as GaN,GaAs,CMOS,and ceramics,was achieved.The microsystem densely integrates two receive channels and one transmit channel.Measurement results show that the output power exceeds 44.9 dBm,the receive gain is 24 dB and tunable,and the noise figure is 5.49 dB.The microsystem has a volume smaller than 20 mm×20 mm×4 mm and a weight less than 4 g,making it 36 times smaller and 19 times lighter compared to traditional circuit modules.This design breaks through the spatial limitations of traditional planar circuits and provides strong support for the overall miniaturization of electronic information systems and innovative applications.关键词
