Product information
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.
Compared to R820T-based devices, this E4000-based SDR excels at sensitivity at <500MHz and >1500MHz, and is capable of far higher frequencies, up to approximately 2350MHz. There is a small gap in frequency capability near 1100MHz. As such,
we do NOT recommend this device for ADS-B usage
. For ADS-B applications, consider the NESDR SMArt instead, NooElec SKU 100700.
SDR improvements
The NESDR SMArt XTR 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 separate silicone thermal pads
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
Antenna improvements
The
included antenna has been redesigned with a wider base
to ensure physical stability with the included longer telescopic antenna mast
A
stronger magnet in the antenna base
facilitates a wide range of mounting options
Low-loss
RG58 feed cable
is used instead of higher-loss RG316 and RG174
Feed cable increased to 2m
(6.5') for easier installations
Male SMA connector on the antenna cable for easy connectivity to the NESDR SMArt and other SMA-input RF devices
Three antenna masts are now included
!  A telescopic mast with a variable frequency capability, a fixed frequency 433MHz (ISM) antenna mast, and a fixed frequency UHF (GSM) antenna mast
