SDR 4T4R Digital Optical Board for Radio, Signal Repeater, Amplifier, System

An SDR Board (Software-Defined Radio Board) is a hardware platform that implements significant portions of a radio's physical layer functions using software-configurable components, rather than traditional fixed analog circuitry.

• RF Transceiver: 4T4R, RF direct sampling, ADC sampling frequency is 2949.12 MHz, DAC sampling frequency is 5898.24 MHz, ADC sampling bandwidth is 100 MHz
• FPGA: Utilizes the domestically produced Ziguang Tongchuang PG2L200H, offers 200K logic elements, equipped with 740 DSP multipliers
• Clock Configuration Chip: Allows for configurable frequency settings based on requirements
• MCU: Responsible for initializing and configuring the clock chip and TR8165-optical, communicates with the FPGA via serial port

Below are the LO and image suppression indicators and TDD-LTE EVM tests (for more detailed test content, please contact us)

1.1 LO and Mirror Suppression Indicators

Test conditions: The signal source inputs a single-tone signal with a power of -14dBm, and after the AT8165-SDR development board, the output power to the spectrum analyser is -5dBm.

2. EVM Data

Test conditions: A 20MHz TDD-LTE signal is input from the signal source at a power of -24dBm, which, after passing through the AT8165-SDR development board, is output to the spectrum analyser at a power of -15dBm.
