This RF circuit measures transmission power from 0.25 W to 10 W. The maximum frequency depends on the diode and the gauge is an analog instrument. A multimeter can be used instead.
This unity gain circuit was found in the February 1995 Electronics Now magazine. The frequency is 10 kHz,...
Found in a 1967 Electronic Design, this transistorized circuit compresses and then expands a pulse....
This TTL pulse stretcher or stretcher was found in a 90's EDN. The time constant R x C1 determines...
