This circuit was obtained from an 80's Radio Electronics. The circuit decodes “scrambled” or sinusoidal encoded signals by providing an audio signal at the output.
We found this RF amplifier in documentation from the 1970s. Field effect transistors support...
This amplifier of approximately 6 W uses complementary transistors at the output, which must be...
