Introducing our innovative DIY Vector Network Analyzer, a perfect blend of functionality and convenience for RF enthusiasts and professionals alike. This compact device is equipped with a 2.8-inch touchscreen and offers TX/RX measurement capabilities, allowing users to accurately determine complete S11 and S21 parameters. For those requiring S12 and S22 parameters, manual reconfiguration of the transceiver port wiring is necessary.

Key Features:

• The device comes with PC control software capable of exporting Touchstone (snp) files, making it a valuable tool for various radio design and simulation applications. The software linked will be provided upon purchase.
• An enhanced frequency algorithm utilizes the odd harmonic extension of the si5351, enabling measurement frequencies up to 900MHz.
• A specially designed metal shield significantly reduces external interference, thereby improving measurement accuracy.
• The VNA-05-900-28’s direct output covers a 50k-300MHz frequency range with over 70dB dynamic, while the extended 300M-600MHz band offers more than 50dB, and the 600M-900M band exceeds 40dB of dynamics.
• Its small, portable design makes it exceptionally user-friendly, ideal for enthusiasts seeking a practical yet powerful RF instrument.

This project is dedicated to providing a handy, yet efficient tool for those passionate about RF technology, combining ease of use with professional-grade features.
