Abstract

Bluetooth wireless technology is a publicly available specification proposed for Radio Frequency (RF) communication for short-range and point-to- multipoint voice and data transfer. It operates in the 2.4GHz ISM(Industrial, Scientific and Medical) band and offers the potential for low-cost, broadband wireless access for various mobile and portable devices at range of about 10 meters. In this paper, we describe the structure and the test results of the bluetooth baseband module we have developed. This module was developed based on IP reuse. So Interface of each module such as link controller UART, and audio CODEC is designed based on ARM7 comfortable processor. We also considered various interfaces of related external chips. The fully synthesizable baseband module was fabricated in a $0.25{\mu}m$ CMOS technology occupying $2.79{\times}2.8mm^2$ area including the ARM TDMI processor. And a FPGA implementation of this module is tested for file and bit-stream transfers between PCs.
