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.
This circuit generates a precise 100 kHz signal. The signal is given by a crystal and can be used...
Using a 12 V transformer, this unit can provide a much higher output voltage. The circuit is from a 90’s...
This circuit was obtained from an Electronics World of 1969. General-purpose transistors can be...
