This simple circuit for switching RF signals was found in an RF Design from the 90s. The circuit operates from 10 to 1 000 MHz and is 50 dB insulated.
We found this circuit very simple in an old documentation. The relay is high voltage sensitive, but...
This circuit was found in an Elektor from the 90s. The circuit uses common components even today,...
The circuit, shown in figure 2, is a monostable multivibrator with two NAND ports out of the 4...
