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.
This circuit generates an FM signal of 4.7 or 10.7 MHz for audio signals on analog TV or FM, with...
This circuit was found in the SGS manual of linear integrated circuits of 1982. The CMRR depends on...
This amplifier is powered by a 9 V source. We found the circuit in a 1964 documentation. The...
