本文主要是研究采用12伏蓄电池做为电源的便携式发射机。射频部分用4个晶体管,在调制器中用2个集成电路系统,输送给功率放大器晶体管的直流功率大约为6瓦,发话波峰的总电流损耗约为1安。
This article focuses on the use of 12-volt batteries as a portable power transmitter. The RF section uses four transistors and two integrated circuits in the modulator. The DC power delivered to the power amplifier transistor is about 6 watts and the total current consumption of the talk-off peak is about 1 amp.
