A frequency counter device up to 12GHz

front view



The device freatures the following functionality:

Working principle:

The counter device is based on the ATmega16 counter that was published already on this site. It uses a prescaler module with a HMC363  integrated circuit from Hittie Microwave to divide the input signal frequency by a factor of 1000. The module is available on flee markets around central Europe. I have purchased it for 50 Euros which I believe is a fair price. The down scaled signal (up to 12MHz at input signals up to 12GHz) can easily be counted the counter circuit which was tested ok up to 70MHz.
