Nooelec NESDR SMArTee XTR SDR – Extended Tuning Range, Bias Tee, TCXO

Description

The Nooelec NESDR SMArTee XTR SDR is a high-performance software-defined radio receiver engineered for demanding RF analysis and monitoring applications. Built around the E4000 tuner and RTL2832U interface chipset, it delivers superior sensitivity across its extended operational bandwidth, particularly excelling below 500MHz and above 1500MHz compared to standard R820T-based dongles. Its architecture includes dual voltage regulators for clean power delivery to the sensitive RF front-end.

Housed in a brushed aluminum case with integrated shielding and a custom heatsink, the device ensures long-term thermal stability and durability in continuous operation. The always-on 4.5V bias-tee simplifies system integration by remotely powering low-noise amplifiers (LNAs) and active antennas, eliminating the need for external power injectors. This SDR is designed for advanced hobbyists, researchers, and professionals requiring reliable, wide-spectrum capture capabilities, though it is not recommended for ADS-B applications.
