论文摘要
在本文中，我们意识到高频（HF）双向收发器无线电的发射器。双向收发器（BITX）由发射器和接收器组成，其中发射器和接收器一起使用一些公共电路。此外，BITX无线电使用单个转换超明近差发送器，该发射机仅在信号生成过程中一次移动频率一次。测量结果表明，它以6.8 MHz的频率工作，使用10 MHz BFO，3,2 MHz VFO和50,3 dBM发射功率。传输频率是从BFO和VFO振荡器之间的差异获得的。 BITX收音机具有简单的电路，设计具有低成本组件，它可能是在偏远地区进行通信的替代解决方案。
In this paper, we realize the transmitter of high frequency (HF) bidirectional transceiver radio. A bidirectional transceiver (Bitx) consists of a transmitter and receiver, in which some common circuits are used together by the transmitter and receiver. In addition, Bitx radio uses a single conversion superheterodyne transmitter, which only shifts frequency once in a signal generation process. The measurement result shows that it works at the frequency of 6.8 MHz with 10 MHz BFO, 3,2 MHz VFO, and 50,3 dBm transmit power. The transmitting frequency is obtained from the difference between BFO and VFO oscillator. Bitx radio has a simple circuit and is designed with low-cost components, and it could be an alternative solution for communication in remote areas.
