Thread Summary

                The user is seeking data on the ADL5513's output noise density below 1kHz for a detector with an envelope bandwidth of 0-100Hz. The final answer suggests that the 1/f noise in the graphs may be influenced by the test setup, and the user measures a standard deviation of 0.002dB (42uV rms) at 100Hz, with a noise density of 4.2uVrms/sqrt(Hz). The user notes that increasing the acquisition bandwidth to 1kHz does not significantly increase the rms noise, indicating low-frequency noise dominance.

Hello, I'm using the ADL5513 for a detector with low envelope bandwidth, around 0-100Hz. The ADL5513 datasheet only describes output noise density down to 1KHz. Do you have any data below 1KHz for estimating output noise? The plots show it decreasing at around 20dB/decade, but I'm assuming it must flatten out at some point...

Mike
