This paper deals with the using of six stages differential pair transisto-f amplifier circuits with low-and-high gain in radar receivers at intermediate frequency(30MC) systems. Because it us.es pair direction cus-off limiting rather than of saturation limiting. To integrate number of minority carriers in transistor base has been avoided. So that response velocity of Receiver intermediate frequemcy systems are very rapid. Small signals after Radar target strength ocho have forcible display. If we accurately select transistors and circuit parameters. Small signals have high gain, but great signals have low gain. Output signals amplitudes-input signal amplitudes have logarithmic relation. Input signal dynamic range have over 80db. If logarithmic begining point puts below 10db receiver noise level. It still has constant false-alarm rate characteristics.

本文阐述了在雷达接收机中频(30兆赫)系统中采用六级双增益级差分对晶体管放大电路时,由于它本身是采用双向截止限幅而不是饱和限幅,故避免了晶体管基区积累大量少数载流子现象。这样使接收机中频(30兆赫)系统响应速度很快,对雷达目标强回波后面的弱信号有较强的显示能力,如果管子及线路参数选得正确时,则可做到:小信号具有高增益,大信号具有低增益,输出信号与输入信号幅度成对数关系,输入动态范围可达80分贝以上。如果对数起点选在接收机噪声电平以下10分贝时,它还具有恒虚警特性。
