Not nearly enough information.Hi, I am using a DC supply to bias a LED. In the middle of my experiment, I found that the DC supply shuts down from 2.2 V to 0 V making a noise and showing a stack of bars on its display. Why does this happen?
If RF voltage is 3V RMS, then bias current not exceed 70mA, therefore unusual behavior of DC supply may arise from RF incursion to DC supply. It may happens by 2 reasons - too small inductance of choke or series LC resonance (choke, capacitor) inside Tee bias.Hi, I am using a DC supply to bias a LED.
