第一款  蓝色 DVB-T+FM+DAB 820T2

These units are based on the R820T2 tuner IC made by Rafael Micro. As such, they have a frequency capability of approximately 25MHz-1750MHz, though this can vary somewhat from unit to unit. There is also an RTL2832U IC on board of course, which acts as the demodulator and USB interface.

The connector type on the antenna and USB board is MCX--male MCX on the antenna, female MCX on the SDR.
