    摘要:

    V频段小型化集成接收前端主要实现对V频段毫米波信号的低驻波、低噪声接收和产品小型化。采用多功能芯片与混合集成技术,实现了毫米波接收信道的小型化集成。引进了微带正交耦合器,构成平衡式分布放大优化射频接收端口输入驻波系数的设计思路,替换了体积笨重的波导宽带隔离器,减小了毫米波接收前端体积和重量。通过对V频段波导微带过渡探针的容错性设计,降低了V频段毫米波接收前端的组装难度,提高了接收前端的一次组装合格率。最终实现批量化V频段小型化集成接收前端射频的输入驻波系数优于1.6,噪声系数优于4.2 dB,外形尺寸(含插座)33.4 mm×30 mm×12 mm。

    Abstract:

    A V-band miniaturized integrated receiving front-end mainly realizes the low Voltage Standing Wave Ratio(VSWR), low noise and miniaturization of V-band millimeter wave signal. In this paper, the miniaturized integration of millimeter wave receiver channel is realized by using multi-function chip and hybrid integration technology. A microstrip quadrature coupler is introduced to form a balanced distribution amplifier to optimize the input coefficient of the radio frequency receiving port, replacing the bulky waveguide broadband isolator, which reduces the volume and weight of the millimeter wave receiver front-end. Through the fault tolerance design of the transition probe of V-band waveguide, the assembly difficulty in the receiving front of the V-band is reduced, and the one-time assembly qualification rate of the front-end is improved. The input standing wave coefficient of the quantization V-band miniaturized integrated receiving front-end Radio Frequency(RF) is better than 1.6, the noise coefficient is better than 4.2 dB, and the external dimension(including the socket) is 33.4 mm×30 mm×12 mm. The V-band miniaturized integrated receiving front-end provides an effective solution for the integrated design and quantitative assembly production of V-band millimeter-wave miniaturization.
