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.
