2 . finline - to - microstrip transitions are designed and used in the power - driver at ka - band 2 .设计了ka频段鳍线-微带的过渡,并将其运用于功率驱动级放大器之中。
The purpose is to escalate 30ghz signals to 35ghz and attain 14db conversion gain by means of power amplifier 其要求是将ka频段30ghz信号通过上变频及功率放大器获得35ghz , 14dbm的射频输出。
The measured back - to - back insertion loss is less than 1 . 0db and return loss is better than 10 . 0db within the entire ka - band 在整个ka频段内实测的背对背插损均小于1 . 0db ,回波损耗优于10 . 0db 。
3 . a 5 - w millimeter - wave power - combining amplifier is implemented and fabricated . the compact bias circuits and power - protection circuits for mmics is designed 3 .研制了ka频段5w功率合成放大器,设计了紧凑的偏置电路和mmics功率单片的电源保护电路。
For ka - band communication antenna , several classes of different satellite weight were considered and the critic first frequency of antenna system was given 为满足ka频段通讯天线的指向精度指标,文中针对不同质量的卫星平台,计算了对天线系统的最小刚度要求。
