AirSpy taking pre-orders for their $199 SDR receiver

From their website:

Airspy is an advanced software defined radio receiver capable of sampling 10MHz of spectrum anywhere between 24MHz and 1.7GHz – and even beyond with extensions. It all started when we needed a good performing receiver that’s still affordable but could not find a good solution in the market, so we designed ours. We believe that as of today, Airspy is the only serious wide band receiver solution that’s high performance and yet affordable.

Some specs:

  • Continuous 24 – 1750 MHz RX range with no gaps
  • 3.5 dB NF between 42 and 1002 MHz
  • Tracking RF filters
  • 35dBm IIP3 RF front end
  • 12bit ADC @ 20 MSPS (80dB Dynamic Range, 64dB SNR, 10.4 ENOB) – Yeah, size does matter.
  • Up to 80 MSPS for custom applications
  • Cortex M4F @ up to 204MHz with Multi Core support (dual M0)
  • 1.5 ppm high precision, low phase noise clock
  • 1 RTC clock (for packet time-stamping)
  • External clock input (10 MHz to 100 MHz via MCX connector) – Ideal for phase coherent radios
  • 10 MHz panoramic spectrum view with 9MHz alias/image free
  • IQ or Real, 16bit fixed or 32bit float output streams
  • No IQ imbalance, DC offset or 1/F noise at the center of the spectrum that plagues all the other SDRs
  • Extension ports: 16 x SGPIO
  • 1 x RF Input (SMA)
  • 1 x RF Output (Loopthrough, U-FL)
  • 2 x High Speed ADC inputs (up to 80 MSPS, U-FL)
  • 4.5v software switched Bias-Tee to power LNA’s and up/down-converters

Thoughts:

From what I’ve read, the big advantage of this over a standard RTL-SDR dongle is much less noise. I haven’t used one, but if it really lives up to their claims the $199 price point is actually pretty reasonable.
