The Design of Low Power Consumption Walkie-Talkie

Abstract:

Communication is very common today, this document introduces a design of high frequency walkie-talkie for communication, and the design of the circuit is low power consumption. The circuit has transmitting circuit, receiving circuit, control circuit and so on, mainly includes mixer, filter, amplifier, frequency modulation (FM), demodulation, microcontroller unit (MCU), liquid crystal display (LCD), keymatrix and so on. This system not only can realise voice communication, but also can transmit short messages. Through the choice of ICs in the circuit, that makes the system to be a low power consumption system. So this system can be used in various conditions.
