This is the SDRx, a specialized RTLSDR which integrates a two-stage LNA (total 30dB of gain), L-band SAW filter (1525 - 1559 MHz), 2PPM TCXO, and two-port USB hub.

SDRx can be plugged directly into a single board computer, such as the Raspberry Pi or CHIP from NTC, or it can be connected by a microUSB data cable (not included).
