EasyEDA project for easy and quick build HF upconverter for work with shortwave bands on SDR receivers. Project include schematic for HF upconverter and PCB's with differences in power circuit (TPS, TPS + LM). 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) **Frequency range:** 0(depends of mixer) - 30MHz; **Power:** USB type B, DC 5 V; DC-005, DC 6.5 - 36 V; **RF connector:** SMA; **Feed line:** 50 Ohm coaxial cable; **Used PCB Material:** FR-4; **PCB thickness:** 1.6 mm; [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] ## List of changes: Version **13.0.EE**: changes of the toggle switch (SW1) on the printed circuit board, now the contacts of the case are soldered to the GND area. The RF line width has been recalculated using [Saturn PCB Design V7.08](http://www.saturnpcb.com/pcb_toolkit/). At the moment, the resistance of the RF line is close to 50 Ohms. Changed the shape of the RF line (added smoothing tracks). ## 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
