    • A direct sequence spread spectrum communication system with a compact automatic gain controller for finely controlling a gain of a received signal. The automatic gain control device may be constructed with a reception signal gain controller for causing an radio frequency amplifier to function as an attenuator during a packet reception interval when the received signal has a level higher than a normal operating level, so as to attenuate a level of the received signal to the normal operating level, and for varying an output level of a local oscillator signal of an intermediate frequency converter upon receiving the received signal having a level which is equal to or lower than the normal operating level, so as to match an output level of an intermediate frequency signal generated by an intermediate frequency stage with an input level of a base band stage.
    • 一种具有紧凑型自动增益控制器的直接序列扩频通信系统,用于精细控制接收信号的增益。 自动增益控制装置可以由接收信号增益控制器构成,当接收信号具有高于正常操作电平的电平时,使得射频放大器在分组接收间隔期间用作衰减器,以便衰减电平 以及用于在接收到具有等于或低于正常操作电平的电平的接收信号时改变中频变换器的本地振荡器信号的输出电平,以便匹配 由具有基带级的输入电平的中频级产生的中频信号的输出电平。
