I'd like to make a circuit that essentially produces very brief bursts of an RF signal, for example RF at 10MHz to 200-300MHz bursts of tens to hundreds of nanoseconds. For example this could be just one half of a sine wave at 10MHz, or for a few cycles of a 100MHz signal. I'm familiar with some techniques for ... WebbI understand this. However I BROKE a pin that is labeled as ground on the pinout diagram meaning that there will be one less connection on the female connector as there is no longer a pin to make contact. thiccboicheech • 39 min. ago.
