Nooelec NESDR SMArt v4 SDR - Premium RTL-SDR w/ Aluminum Enclosure, 0.5PPM TCXO, SMA Input. RTL2832U & R820T2-Based

You spoke, we listened! This premium RTL-SDR was designed, developed and fabricated by Nooelec in the USA and Canada in order to implement a wide array of feature requests.

SDR improvements:

• 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.
• 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. That is at least 10x lower than other designs!
• A quality shielded inductor was used in the power supply to improve EMI rejection.
• The included aluminum enclosure ensures stray EMI stays where it belongs--away from the sensitive RF circuitry.
• Lower board-level temperatures further improves the SDR noise floor.

Temperature improvements:

• 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.
• 2 pieces of silicone thermal pad spread the rest of the heat away from the device hot spots.
• Power consumption has been reduced by an average of 10mA, which means less heat is generated compared to other designs.
• The result is much lower board-level temperatures--increasing stability, improving sensitivity and ensuring maximum frequency range capability. The changes were first simulated, and then field-tested with a Flir E8.

Form factor improvements:

• The NESDR SMArt was designed to minimize annoying USB port occlusion. We re-designed the SDR from the ground up to ensure the SMArt can be used side by side in any USB-compliant device, including tightly-spaced embedded devices. There is no need to remove the enclosure to run multiple SDRs beside one another!
• The form factor re-design allowed us to move to the more universal SMA antenna input.
