This Schmitt trigger in current mode for frequencies up to 50 MHz was found in a 1969 Motorola manual. Appropriate switching transistors can be used.
This 80's Motorola circuit can generate 100 MHz signals, but they can reach 200 MHz with the...
Of course, the current is extremely small, but a voltage of 300 V can be obtained from 9 V of a...
We found this solid-state relay circuit that can function as a shield in a Radio Electronics...
