This circuit is from a documentation on the MC1539 from Motorola and may, however, be implemented with equivalent operations. The transistor also supports equivalent.
We found this project in a 2002 documentation. The transistor amplifier has a power of a few watts...
This circuit is from 1995 documentation. In the original, the source is symmetrical at 12 V, but...
Here we have a transceiver for the amateur radio range, which operates in the 40 m band (7 MHz),...
