This TTL circuit is from a Radio Electronics magazine from February 1973. The circuit must be powered with 5 V and the maximum frequency depends on the TTL integrated circuit.
This circuit is basically the same configuration as the previous one with a power stage with...
Found in a 1969 documentation, this circuit for the 20 MHz band does not use a transformer. The circuit is...
This circuit can provide a voltage of up to 900 V depending on the input voltage. The diodes must...
