EasyEDA project for easy and quick build "Coax power supply, fixed voltage" module used for powering up active antennas and amplifiers through a coaxial cable. 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: [-tested-green.svg)](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; **Frequency range:** 10 MHz - 10 GHz (according to the datasheet on TCBT-14+, upper frequency may be unattainable with FR-4 PCB material); **Output voltage:** DC +3.3 V (can be changed by replacing the linear regulator LP5907MFX-3.3); **Maximum output current:** 200 mA; **RF connector:** SMA; **Feed line:** 50 Ohm coaxial cable; **Used PCB Material:** FR-4; **PCB thickness:** 1.6 mm; **PCB copper weight:** 1 oz; **Used only to power receiving antennas or amplifiers! Using the device in a transmitting radio channel can damage the TCBT-14+ (maximum allowable power is 30 dBm).** [EasySDR project page at GitHub][1] Buy SDR receiver: [RTL-SDR.COM][2] Buy TCBT-14+ Bias Tee: [Mini-Circuits TCBT-14+][3] [Order PCB manufacturing using PCBWay service][4] ## 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://www.rtl-sdr.com/shop/ [3]: https://www.minicircuits.com/WebStore/dashboard.html?model=TCBT-14%2B [4]: https://www.pcbway.com/QuickOrderOnline.aspx
