This oscillator with emitter follower was found in an American documentation from the 80's. The circuit generates 100 MHz signals and the transistors admit modern equivalents.
Found in Harris' 90s documentation, this circuit uses a zener as a stabilizer. The signals...
The integrated circuit used in this small transmitter is not very common today. The coil has its...
The resistors R1 and R2 consist of 8 220 ohms x 2 W resistors connected in parallel. The...
