Abstract

Bluetooth was started from concept that connected in all communication environments by single equipment integrating different communication devices. Wireless communications of today are using cellular phone, broadband wireless service, home RF, Bluetooth that supports data and voice and so on. Among these, Bluetooth is very useful wireless communication method. In this paper, a design and implementation method of wireless digital amplifier for mobile IT devices is presented. Efficiency of analog amplifier is low and it has disadvantage that do not attach cooling fan by noise of inside. Moreover external form size of analog amplifier can´t but be big because of heat sink. Therefore, analog amplifier is not suitable to mobile IT device. And today, it is trend that most IT devices that have wireless communication functions.
