Editor’s note: This is the first part of a two-part design idea (DI) that shows how modifications to an oscillator can produce a useful and unusual pulse generator; the second and final part extends ...

Everyone interested in analog electronics should find some value in this post. Of course, an effort has been made here to make the content understandable to relative newbies. Forget about complex ...

Metamaterial-based backward wave oscillators (BWOs) represent a significant advancement in the generation of coherent microwave radiation. These devices exploit engineered metamaterials—materials ...

A long thin glass tube with a metal cap on the bottom and six pins, a contact and an exhaust tip on top. Donor’s card reads: “Backward wave oscillator made by Stewart Engineering Company, Santa Cruz, ...
