摘　　要：介绍一种用于抛掷敏感器的结构紧凑的 Ka-波段微带集成本振 -混频组件 ,给出了该组件的微带电路结构 ,叙述了其中每一部件的功能 .对该组件仔细做了环境和可靠性实验 ,其中包括震动 ,冲击和温度 .在 2 GHz射频带宽内 ,该组件的双边带噪声系数是 3.4～ 4.2 d B,在其工作频带内本振到射频的隔离度大于 2 7d B.由于使用了介质谐振器 ,本振的频率稳定度小于 6 0 ppm/℃ .A compact Ka-band microstrip integrated local-oscillator-mixer assembly used in projectile sensors was introduced. The overall configuration of microstrip circuit of this assembly was given. The functions of each component were described. The environment and reliability tests performed on this assembly were explored in detail, which include vibration, shock and temperature. The Ka-band local-oscillator-mixer assembly exhibits a 3. 4 similar to4. 2-dB double side band (DSB) noise figure over a 2-GHz RF bandwidth. LO-to-RF isolation is greater than 27dB over the range of operating frequencies. The frequency stability of local oscillator with dielectric resonator used is less than 60ppm/degreesC.
