2.4 GHz Spectrum Analyzer Circuit Nokia 3410 LCD ATmega8
Mobile phones with Nokia 3410 LCD screens often used microcontrollers Atmel ATmega8 and cywm6935 nokia 3410 LCD modules made with a 2.4 GHz spectrum analyzer circuit.
Handheld 2.4 GHz Spectrum Analyzer Circuit
After visiting some web pages about 2.4 GHz ISM band spectrum analyzers based on the CYWM6935 module, I tried to build my own analyzer, but with some improvements.

I want the analyzer to be portable, and easy to transport, so I will use a microcontroller and a graphical LCD.
