good circuits

I'm looking for good circuits on PIC or AVR frequency meter for 2GHz.

frequency meter mb506

You may look this project. It has two inputs. First is for frequencies up to 62 MHz and second up to prescaler frequency limit. It can be even 3.5GHz.
I realized it and find OK. Prescaler can be any type with required divide ratio and high enough upper frequency limit.

avr+frequency meter

Hi,

What do you want to do with 2ghz frequency? Will you measure something or control?
Please elaborate it..

Analyzer.

f5jtz tos metre

The Hittite IC company makes low cost prescalers that will drop the frequency into the range of low cost counter.

avr frequency meter circuit

I MADE A CMOS CASCADE CMOS DRIVEN MATRIX LED DISPLAY
IT USED 1MHZ REFRESH OF THE LED MATRIX MUX SO THE LED UPDATES AS PER YOUR DIVISION EXACTLY {LOTS OF LEDS DONT SO GIVES A FALSE ILLUSION SLURRING YOUR MEMORY OF THE EVENT AS YOU TUNE} WAVES IN THE BRAIN
ALPHA BETA GAMA DALTA EPSILON -1KHZ - 1 MHZ RESPONSE LEVELISED

LOTS OF ENGINEER COMPLAIN

BEST "REFRESH" TYPE COUNTER I FOUND WAS A NIXIE TUBE FOR NON MEMORY SLUR WHILE TOO TUNE SO I DESIGN MY OWN}

THIS STOPS SLOW FLICKER AND REFRESH PROBLEMS

TAKING THE TOTAL COUNT DOWN TOO A BINARY ROW PIN CARD TYPE MATHS REPRESENTATION OF THE FREQ

INSTEAD OF USING CONVENTIONAL GATE AND COUNT

I USE SAMPLE AND HOLD

THE HOLD WAS HELD AND THE HELD SAMPLE WAS REFRESHED @ 8 MHZ THE ROWS WERE REFRESHED LIKE A PIN BOARD OF THE RT SAMPLE IN DATA TERMS - SOME FREQ

I DEDUCTED WITH A DIGIMETRIC PRESCALLER
I THINK WAS AN AD SOMETHING CHIP ILL LOOK OUT THE SCHEMO

GATE AND COUNT BY CASCADE IS STUPIDO

SAMPLE THE GATED HELD IS LIKE PI METAL DETECTOR TECHNIQUE

AND IS FASTER LATENCY IN RT THAN MOST PLL'S LOCK


ONE THING I LEARNED IS THIS


IF GRAVITY EXISTS AND IT DOES

IT GOES UP AS WELL AS DOWN MUCH LIKE COLUSIVE LAW


OF MOTION OF A BODY IN AN ATMOSPHERE

SO....... THE BODY OF RADIO THESE DAYS PREFERS TOO USE THE IMAGE OF THE FREQ AND THEN DOWN CONVERT {DOUBLE HETRODYNE}


SO WHY STICK A FREQ COUNTER AS A SINGLE HETRODYNE DEVICE

AS PER GATE AND COUNT TECHNIQUE

HOWEVER PIC IT IS DONE

2 PINS ON A CPU IS BETTER THAT 16 AND 32 I/O WORD

I DONT THINK SO......

frequency meter pic ghz

u can use a simple timer counter in ucontroller, 8051 pic avr, then use the prescaler ic to increase the freq. range but it will decrease the resolution.
