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 circuit is from the Motorola Linear Databook published in 1990. The circuit for 1 kHz can be...
This simple injector circuit can actually be powered by voltages from 3 to 9 V. The frequency is...
This stair generator uses an R/2Fl network to determine the amplitude of the steps. This circuit...
