The device is intended to use in low power measurements because his limits: -45dBm to 15dBm.
Is based on MAX9933 as logarithmic detector and ATMEGA 8 for calculation and display the level of power.
Because the specifications of MAX 9933, i had to brake the entire frequency band (1-1600 MHz) in three sub-bands to improve accuracy.
