Found in American documentation from the 1990s, this circuit generates signals in the 350 to 500 MHz range. The output power is in the order of 100 mW at 50 ohms.
In figures 1 and 2 we have two current drains that can be made with operational amplifiers and...
Great sensitivity for the circuit can be obtained with a Darlington amplification step for the...
The used diode is an unusual component today. We found this 12 V regulator in documentation from the...
