Power consumption has been reduced by an average of 10mA, which means less heat is generated compared to other designs.

2 pieces of silicone thermal pad spread the rest of the heat away from the device hot spots.

A custom heatsink is affixed to the primary PCB with 3M thermal adhesive, to wick heat away from the circuit board and towards the enclosure.Lower board-level temperatures further improves the SDR noise floor.The included aluminum enclosure ensures stray EMI stays where it belongs-away from the sensitive RF circuitry. That is at least 10x lower than other designs!Ī quality shielded inductor was used in the power supply to improve EMI rejection. In the quest for lower noise, the power supply section was redesigned to implement an RF-suitable voltage regulator with under 10 µVRMS of noise. The NESDR SMArt contains the same ultra-low phase noise 0.5PPM TCXO used in our much smaller Nano 2+ (TCXO specifications below), ensuring ultimate tuning stability in nearly any environment.
