Features 1、【High Frequency and High Data Processing Capability】: This software-defined radio receiver has a 1MHz to 6GHz wide operating frequency, covering most radio frequency bands. Its high-speed data processing capability of up to 20 million samples per second guarantees the accuracy and efficiency of signal processing. It adopts 8-bit quadrature sampling technology to ensure high flexibility in receiving and transmitting signals. It is a powerful half-duplex device for R/u0026D and testing for radio technologies. 2、【Software Defined and Highly Configurable】: As an open-source hardware platform, users can customize and develop it freely according to their needs. It supports mainstream software such as GNU Radio, SDR#, etc. It is easy and flexible to use, and users can conveniently configure the RX/TX gain, baseband filter, and software-controlled antenna port powersupply (50mA at 3.3V) via software. It supports firmware upgrades to ensure continuous performance optimization and technology updates. 3、【Optimized Design and Accessory Enhancement】: The product has upgraded circuit design, such as using MAX2839 to replace MAX2837, using Si5351A with additional clock distribution to replace Si5351C, and adding series diodes at the antenna port powersupply. A new 10.00MHz TCXO 5070 crystal oscillator has been added to improve the frequency stability and accuracy. In addition, the integrated built-in microphone features a new CPLD code so the reboot button doesn/u0027t freeze the device, and a 3.2-inch 240*320 TFT screen and navigation switches to provide a better user experience. 4、【Convenient Connection and Operation】: It provides an SMA female antenna connector, an SMA female clock input/output for synchronization, as well as convenient programming buttons and internal pin headers for expansion, and supports a Hi-Speed USB 2.0 interface for USB power supply. Meanwhile, it provides audio output and microphone input connectors for more application scenarios and possibilities. 5、【Premium Material /u0026 Long Lasting Durability】: The device is made of a 4-layer gold-plating process and has a transparent drop-proof housing with enough strength to resist external pressure, ensuring stable performance and a long service lifespan, which improves the durability and stability of the device. It is a reliable SDR platform for professional radio developers, test engineers, and hobbyists.
