Vantech Green Mini RTL2832U R820T DVB-T SDR DAB FM USB DIGITAL TV Tuner Receiver RTL-SDR Project + DAB dongle Tuner MCX Input

- fit for RTL-SDR Project DVB-T Tuning Range (approximate)
- Runteck Original DVB-T FM + DAB
- Up for sale is based on the R820T (can be the replacement of E4000)tuner IC made by Rafael Mirco

Sticks with this combination (RTL2832 + R820T) are relatively new on
the market. The main difference to all the other supported tuners so
far is that it uses a Low-IF (3.57 MHz) architecture instead of
Zero-IF. That means the tuner is only connected to the In-Phase ADC
input, and the internal down converter of the RTL2832 is generating the
complex samples. This has the benefit of having no DC offset spike in
the middle of the spectrum.
