Re: SDR Micron - 14-bit Direct Digital Conversion Receiver with USB connection

Hi David,

My Micron using ADS6143.
I masseur again.
About 160mA when inactive mode.
About 360mA when active mode.
I don't know why.....?

When 0.1uF and 1nF were jumpered, the sensitivity of the low band
increased. The sensitivity is equivalent to HiQDRmini.

Hello, Leo

370 mA is in inactive mode when ADC is powered down. Try to messure in active mode, when receiver is working.

SDR Micron is using 270 Ohm feedback resistor instead 499 Ohm in HiqSDR mini.
This is matched to 15дБ gain instead 20 dB gain in Hiqsdr mini.
