    It's very cool that you share old school techniques, because a pro knows when older methods are still the best solution.

    This is the Thing !!!
    is there also Analogue multiplayer ?

    Curious if there are ever issue with the startup time.
    If no filters are employed, I'm also wondering what all possible frequency conditions it could 'lock' onto.

      The transistor used has a lot of gain.. so I think the startup condition is pretty fast. Actually all the microstrip structures are filters, so it only works for the design frequency (maybe multiples)

    I got 2 questions: #1 - If the Speed of Light is 299,792,458 meters pers second, and I assume the velocity of the speed of waves in copper is 95% of "c", then am I correct to conclude that: 299,792,458 times 95% is 284,802,835.1 meters per second, divide by 800 million, you get a full wave (in copper) of .356 meters, which I converted to 14 inches full wave. So, are your copper strips 14 inches in length, 7 inches in length, or 3 1/2 inches in length? #2 - How far can you move away from your 1.6 Ghz input can you go before you no longer get 1/2 on your output ? Will 1.4 Ghz input give you 700 Mhz, or will you be too far from the center, to get "center" ?

      Hi Jeremy. The wave speed in an FR4 PCB is around 45% the speed of light.
      The circuit works only for narrow signals, where the filters are tuned. Like 5MHz out of center.

    Excellent work. Are these micorstrip lines all made by copper tape on a one sided PCB?

    hi i want to record and digitize rf signals in 2 ghz with real time sampling my rf signal isnt repeatitive can I use this frequency divider to decrease signal frequency to record it with lower sample rate digitizer?

    • @AllElectronicsChannel

      I think no!

      @@AllElectronicsChannel what can I do is there any way to down converting not repeatitive signals ? as you know we can digitize high frequency signals with equivalent time sampling techniques but signal must be repeatitive!
      please help.thanks

    7:25 two transistors so it's not completely Passive
