The following page outlines detail information regarding the design of a simple Universal UHF/VHF frequency meter circuit board and PCB Layout. This circuit design uses a 7-digit frequency meter measuring frequency from 10 Hz up to 1300 MHz. It is based on ideas of PIC16F84 based frequency meter. The measuring range is divided into two subranges: 10Hz – 25MHz and 25 MHz – 1300MHz.
Universal UHF | VHF Frequency Meter Circuit Parts List:
PIC 16F84
74HC137 (BCD -> 1 of 8 decoder)
SAB6456 VHF-UHF divider by 256
7-digit calculator display (common cathode),
some resistors, capacitors and 2 switching diodes
