high frequency

Hi, I am looking for a transistor that I can use as a switch at a minimum frequency of 10 MHz. So far, I haven’t been able to find a suitable component, and I would really appreciate your assistance or recommendations. My circuit is intended to look like this: Thank you very much for your help.

Hello everyone, I'm currently making a test machine for testing (voltage, frequency) PCBs. There are 5 test points on PCB where I need to measure frequency 20MHz. So, I'm using relay to switch around test point and connect to the probe of my oscilloscope (Keysight DSOX1202a). I've found out that...

I'm looking into a way to construct a circuit that can generate ~200MHz negative voltage sine waves (8 channels), where there is 11 degrees of phase offset between the channels (0 deg, 11 deg, 22 deg, ...). I would like to be able to adjust the frequency, phase offset and possibly amplitude of...

HELP!!! so, the thing is that i have been trying to build a resonant high frecuency circuit to control a variable capacitor, this capacitor can support high voltage and high frecuency but its variable due to the electrolite it contains.. so I have been tryin to desing it and have come with a...

Hi. I plan to make a pcb that drives peltier and heating pad. Only one of those works at the same time. Load elements are parallel to capacitors. I have very little space on pcb so it would be nice if I could use only one inductor as it is in screenshot. I know it would be easier just to put...
