摘要
对讲机、手机电池每充一次电的使用时间只能按小时计算，是众所周知的事实。本文针对对讲机，介绍一种能既不影响守候信号，又可以成若干倍地增加电池使用时间的电路，并给出了电路设计参数，具有实用价值和较好的经济效益。
It's known that the battery capacity of transceiver and move telephone is limited so that the worktime is counted by the hour. This paper has introduced a circuit for the transceiver, which can increse the battery's using time without any effect on receiving signals. Design Data have been provided in this paper, which are practical and have good benefit.
