Exclusive 2.5 GHz Frequency Counter

 


A frequency counter is one of the most important measuring tool we need as homebrew's of RF electronic. This frequency counter has very high performance and still is very easy to build and to use. Anyone can build it and have a professional frequency measuring tool. The counter is based around a LCD display with 2 lines and 16 chars. I have used a HD44780 based display which is very common. A PIC16F870 circuit controls all counting and display functions. A prescaler is added to make it possible to measure up to 2.5GHz with high sensitivity. The Display Module Size (W x H x T): 80mm X 36mm. The controller PCB has the same size. This makes the unit very small and slim.
