| The rapid development of wireless technology makes the low frequency band extremely crowded and millimeter wave can provide abundant spectrum resources.With the maturity of millimeter wave theory and technology,the improvement of circuit integration and the reduction of cost,millimeter wave technology is more and more widely used in millimeter wave communication,vehicle-borne radar and other fields.This thesis focuses on the design of millimeter wave transceiver front-end and key components.The main contents include:(1)A set of four bandpass filters for Q-band millimeter wave near-long range ultra-high throughput communication standard(Q-LINKPAN)superheterodyne transceiver are designed in 0.13?m Si Ge Bi CMOS technology,including transmitter IF/RF filters and receiver IF/RF filters.The filters have the characteristics of miniaturization and high stopband rejection.Good test results have been obtained.For the 13GHz transmitter IF filter,the chip area is only 0.26×0.33mm~2,and the stopband roll-off rate is more than 10d B/GHz.And for the 45GHz receiver RF filter,the area is 0.17×0.18mm~2,and the minimum insertion loss in band is 2.8 d B.(2)A Ka-band power amplifier is designed in 0.13?m Si Ge Bi CMOS technology and the design adopts two-stage differential cascode structure.The test result shows that the 3d B bandwidth of this amplifier is 31GHz-39.3GHz and the maximum small signal gain is 29d B.In the 3d B bandwidth,S11 is less than-5.3 d B,and S22 is less than-9.36 d B.The saturated output power and peak PAE at 36 GHz are 19.43 d Bm and 20%respectively.(3)A W-band linear frequency modulation continuous wave(LFMCW)radar front-end with one transmitter and two receivers is designed.The output transmitting signal frequency range is from 81.24 GHz to 85.92 GHz.The phase noise of 82.8 GHz signal from the antenna at 100 k Hz,1 MHz and 10 MHz offset are respectively-58 d Bc/Hz,-89 d Bc/Hz and-98 d Bc/Hz.The radar front-end can achieve good sweep linearity and range detection function. |
