bladeRF 2.0 micro xA5

The bladeRF 2.0 micro xA5 is the next generation Software Defined Radio (SDR) offering a frequency range of 47MHz to 6GHz, 61.44MHz sampling rate, and 2×2 MIMO streaming. Packed into a small form factor, the bladeRF 2.0 micro was designed for high performance as well as mobile applications. Through libbladeRF the bladeRF 2.0 micro is compatible with GNURadio, GQRX, SDR-Radio, SDR#, gr-fosphor, SoapySDR, and more on Windows, Linux and macOS.

The RF shield cap protects sensitive RF components from Electromagnetic Interference (EMI) and provides additional thermal dissipation, allowing the bladeRF 2.0 micro to operate in challenging environments.

All of the RF SMA ports are capable of providing power over bias-tee circuitry to wideband amplifiers and pre-amps. Power to bias-tee peripherals is fully software controllable, providing maximal operational flexibility. Currently, the official bias-tee peripherals include the BT-100, a wideband power amplifier for TX, and the BT-200, a wideband low noise amplifier for RX.

At the core of the bladeRF 2.0 micro is the latest generation Cyclone V FPGA from Intel (formerly Altera). The xA5 features a 77KLE FPGA of which about 60KLE are available and user programmable. An advanced clocking architecture allows the bladeRF 2.0 micro to receive and provide its 38.4MHz fundamental clock from and to other devices. Additionally, an on-board PLL allows the bladeRF 2.0 micro to tame its VCTCXO to a 10MHz reference signal. The xA5 features a highly accurate and stable oscillator. The on-board DAC sets the frequency trim of the oscillator to a factory calibrated value.

The Power Distribution Network (PDN) of the bladeRF 2.0 micro features an intricate combination of low noise and high efficiency switch mode and linear power regulators. While the bladeRF 2.0 micro can be run solely from USB bus power, an external power source can be supplied to ensure maximal linear performance of bias-tee peripherals. The PDN features an auto selection and hold-over circuitry to optimize power draw between USB bus and external DC power.

The bladeRF 2.0 micro can run in headless without needing to be connected to a PC or SBC. The on-board flash is large enough to hold any size FPGA image for the xA5.

bladeRF 2.0 micro xA5 Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

4 Programming

Skill Level: Experienced - You will require a firm understanding of programming, the programming toolchain, and may have to make decisions on programming software or language. You may need to decipher a proprietary or specialized communication protocol. A logic analyzer might be necessary.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
