My First Oscillator 45-years Ago


This worksheet will give the design of in-line cavity resonator used in my oscillator 45-years ago. The tube was 5893-pencil type or 2C40-lighthouse type. At that time there was no Mathcad available and it shows the difficulties in calculations without Mathcad. Later designs were based on microwave semiconductors based on Y/S parameters or Bessel functions for low phase noise. Enjoy reading.

Thanks it brought back some memories for me.

Fine!

But why do you not use units. Now (45 years ego) we can do it! With Mathcad!

Yes Sir, For simplicity I did not use units, but I did with my previous worksheets. Thank you
