Funcube Dongle Plus Pro information

1. Funcube Dongle Pro+ front-end chip is Mirics's MSi001(or Msi002). Its block diagram show 6-ways LNA to cover different impedance and frequency range. RF signal is down-converted to LIF or ZIF and seperated to I/Q signal. The I/Q signal is filtered and amplified for ADC.

2. Mirics provide IF IC - MSi2500 to get ADC resolution to 10bits. It is better than RTL2832 in 8 bits. The highest sample rate  reach 12Msps. Due to the USB 2.0 HS(480Mbps), the selected sampling rate is about 2 to 3Msps.

3. FCDP use the audio codec with maximum sampling rate to 192Ksps. For Funcube satellite, it is adequate. There is another SDR USB dongle called SDRplay using FE filter+MSi001+MSi2500 to get wider signal bandwidth and better noise immunity.
