EasyEDA project for easy and quick build "HF Upconverter" module used for working with [LF](https://en.wikipedia.org/wiki/Low_frequency), [MF](https://en.wikipedia.org/wiki/Medium_frequency) and [HF](https://en.wikipedia.org/wiki/Shortwave_radio) bands on SDR receivers. Project includes schematic and PCB prepared for setting up into aluminum enclosure with dimensions 80 x 50 x 20 mm with SMA connectors. Version for mounting SMD components. ## Current development progress: [](https://github.com/IgrikXD/Easy-SDR) [](https://github.com/IgrikXD/Easy-SDR) [](https://docs.google.com/forms/d/e/1FAIpQLSeUFM1p15N_vk8X_blSnZp6jPlZe_qRhiRlmntscx6jF2yRqw/viewform?usp=sf_link) **Input voltage:** USB type B, DC 5 V; **Input frequency range:** 0.5 - 65 MHz; **Output frequency range:** 125.5 - 190 MHz; **RF connector:** SMA; **Feed line:** 50 Ohm coaxial cable; **Used PCB Material:** FR-4; **PCB thickness:** 1.6 mm; **PCB copper weight:** 1 oz; [Easy-SDR project page at GitHub][1] Original schematic: [Upconverter 125MHz v1.3 - Passive Upconverter Hardware Design for SDR][2] Buy SDR receiver: [RTL-SDR.COM][3] Buy ADE-1 mixer: [Mini-Circuits ADE-1][4] [Order PCB manufacturing using PCBWay service][5] ## How to contact me? - E-mail: igor.nikolaevich.96@gmail.com - Telegram: https://t.me/igrikxd - LinkedIn: https://www.linkedin.com/in/igor-yatsevich/ [1]: https://github.com/IgrikXD/Easy-SDR [2]: https://github.com/opendous/Upconverter1v3 [3]: https://www.rtl-sdr.com/shop/ [4]: https://www.minicircuits.com/WebStore/dashboard.html?model=ADE-1%2B [5]: https://www.pcbway.com/QuickOrderOnline.aspx
