Description

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:

Progress Progress Bug report

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;

Original schematic: Upconverter 125MHz v1.3 - Passive Upconverter Hardware Design for SDR
Buy SDR receiver: RTL-SDR.COM
Buy ADE-1 mixer: Mini-Circuits ADE-1

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. At the moment, the resistance of the RF line is close to 50 Ohms. Changed the shape of the RF line (added smoothing tracks).
