| Abstract: | This paper introduces an innovative experiment on design of a short-wave transceiver with the mobile network control, which uses 7.023 MHz short-wave band and can communicate between devices within hundreds of kilometers. The basic circuit in the communication electronic circuit is used to design the unit circuit and construct the system, and at the same time, the mobile interconnection control module circuit is added. The design of the transceiver includes the antenna, input signal processing module, mixer module, audio signal output module, control and Wi-Fi module, etc., which is very suitable for the comprehensive experiment teaching of communication electronic circuit. Through the experiment, students can fully understand and master the working principle and design method of transmitter and receiver. |
