Description: The bladeRF x40 is an affordable USB 3.0 Software-Defined Radio (SDR) designed to allow students and RF enthusiasts to explore wireless communication, and to provide professionals with a versatile COTS waveform development platform. The bladeRF x40 is a great next step after using an SDR like the HackRF One, especially with the built-in FPGA providing you with more user-defined options.

Out of the box, the bladeRF can tune from 300MHz to 3.8GHz without the need for extra boards. Through open source software such as GNURadio (live image), the bladeRF can be placed into immediate use. With its flexible hardware and software, the bladeRF can be configured to operate as a custom RF modem, a GSM and LTE picocell, a GPS receiver, an ATSC transmitter or a combination Bluetooth/WiFi client, without the need for any expansion cards.

    The 300Mhz cut-off kinda kills most SDR non-sat communication projects except 70cm applications. Need at least down to 100Mhz for AIS and 2M projects and down to 500khz would open up all the HF bands!

    Look forward to seeing a future product.

  • Looks like fun. Too bad it bottoms out at 300 MHz. I’d actually be interested in one that worked between 500 KHz and 1.3 MHz without external boards or mods. Is that in the works?

  • $420? were the guys in the pricing department high? [Joke successfully deployed]

  • Check out this SDR device designed in UK. The crowdfunding has finished and now you can order one from here I dont know much about SDR but this looks very capable 100KHz to 3.8GHz

  • Does anyone know of a good enclosure for these?

  • “The XB-200 is a block up-down converter that greatly expands the bladeRF’s usable frequency range down” LF/MF/HF/VHF transverter (60kHz to 300MHz)

    • Thanks, but it’s an external add-on (like the iphone dongles), it’s an additional $200 and it’s out of stock. Still looking for a version that covers 500 KHz to 1.3 GHz with no add-ons needed. Should be simple for them to design/build one - it’s only half the bandwidth and it’s down at the easy end of the spectrum.

    • You beat me to it. $620 for an SDR from 60 kHz to 3.8 GHz sounds like a pretty good deal!

do not work with raspberry 3

i can not get work like i read in the articles “”,and the sdrsharp with windows “BladeRF + SDR# on Windows 10"please help me to understand i am newbie on that device,thanks,sorry for my english,if youvae some info on spanish woulbe cool.
