AFEDRI SDR has next parameters:<\/p>\n

RX frequencies:
\n0.1MHz-30MHz (Low Pass filter assembled (LPF) – default assembly configuration)
\n0.1MHz-150MHz (In aliased mode, LPF is not assembled, external Band Pass Filter (BPF) have to be used instead)
\nNoise Figure: ~17dB (for 1MHz-30Mhz range)*
\nNoise Figure: ~24dB (for 144Mhz band)*
\n*input VGA (Variable Gain Amplifier) is tuned to have variable Gain from -6dB up to +44dB
\nOutput data format: two 16-bit I\/Q channels (audio stereo stream emulation)
\nMaximum Receiving bandwidth:
\nBW = up to 240kHz (for 250 ksamples\/s sample rate) – 192k version (current design revision)
\nBW = 90kHz (96ksamples\/s) – 96k version (old design revision)
\nRF ADC sampling rate: 76.800MHz (or alternatively 79.872MHz)
\nPower Supply Voltage: 5V (supplied from USB bus)
\nPower Supply current: 330mA<\/p>\n
