The AD9371 software radio platform (mexc global官网9371-SDR) is a high-performance SDR development board launched by our company in conjunction with ADI's RadioVerseTM technology.
mexc global官网9371-SDR Selected for ADI RadioVerseTM Third-Party Reference Design
mexc global官网9371-SDR software radio platform features:
1. Based on Hejiaxing's mature product design, not only can you test and evaluate the AD9371 chip, but you can also launch your own product directly through simple custom modifications to the development board, which really accelerates the conversion process from design concept to finished product;
2. We will provide complete mexc global官网 source code, ARM source code, platform schematic diagram, and related design materials and documents to users who purchase mexc global官网9371-SDR;
3. Digital, hardware and RF engineers provide technical support.
1.mexc global官网9371-SDR System Block:
5. Digital signal processing unit: adopts Xilinx's new-generation Artix-7 series mexc global官网, which has rich DSP and Logic resources, and is compatible with 7A100T / 7A200T at the same time, which is convenient for customers to choose according to specific project conditions. Relevant variable parameters (including the function selection of each module in the mexc global官网, peripheral DSA chip attenuation, AD9371 chip frequency, etc.) can be directly modified on the host computer through the serial port. The following is the mexc global官网 framework when receiving a data rate of 122.88M and transmitting a data rate of 245.76M. When sending and receiving the same data rate, no up-conversion module (Up2) is required. The DATACAPTURE module can choose to capture data of a certain depth from RX / TX / ORX and transmit it to the upper computer through ARM, which is convenient for users to do spectrum analysis directly on matlab. The MUX module can select the signal source output from the transmitting end, including the DDS single tone output, the RX end signal, and the ORX end signal of the mexc global官网.
4.Test Results
The following are LO and image suppression indicators and TDD-LTEEVM tests (please contact us for more detailed test content)
(1).LO and Image reject performance
Test conditions: single-tone signal mode, the input power of the signal source is -14dBm, and the power output to the spectrum analyzer after the mexc global官网9371-SDR development board is -5dBm.
(2).EVM performance
EVM test conditions: TDD-LTE signal mode, 20MHZ bandwidth, signal source input power is -24dBm, after mexc global官网9371-SDR development board, the power output to the spectrum analyzer is -15dBm.
