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.
