This circuit was suggested by Texas Instruments in a 1980s documentation. The transistor must be equipped with a heat sink. The transformer has 10 A secondary current.
Details of the coil of this two-transistor generative receiver were not given. We found it in a...
This very high input impedance circuit is suggested by Texas Instruments. The circuit can be...
This circuit from an 80's publication also features low input capacitance. FET can be a modern...
