Portable 2.4 GHz Spectrum Analyzer using Atmega8 microcontroller




There are plenty of wireless devices available on the market that broadcast in the 2.4 GHz ISM band. Such devices include Bluetooth, WiFi, Zigbee, wireless USB, cordless phones, wireless mice and keyboards, etc. This project describes a wireless spectrum analyzer to examine the surrounding radio frequencies in 2.4 GHz band.

Portable 2.4 GHz Spectrum Analyzer

The project is based on the Cypress’s CYWUSB6935 radio module. It is a complete radio module with PCB trace antenna and it operates in the unlicensed Industrial, Scientific, and Medical (ISM) band (2.4 GHz- 2.483 GHz). The radio module is interfaced with an Atmega8 microcontroller, and the recieved spectrum is displayed on a Nokia 3410 LCD. The microcontroller, the Nokia LCD module and the radio module are all operated at 3.3 V power supply. The firmware is developed in C using AVR GCC for Windows (WinAVR).
