This circuit, very critical due to the frequency at which it operates, was found in an American documentation that uses a resonant cavity in a beer can. The transistor can be of any type for RF.
We found this circuit in the Linear Applications Handbook of the National Semiconductor of 1994....
This tone-modulated transmitter was found in recent English documentation. The circuit operates in the 27...
This very low current circuit was found in the April 1995 issue of Electronics Now magazine. The...
