EasyEDA project for easy and quick build LNA module. Project include schematic for LNA module and PCB's with differences in the power circuit and Bias Tee implementation (PCB with/without reverse polarity protection circuit, PCB with/without TCBT-14+ Bias Tee module). 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:** DC 6.2 - 15 V (external source) / DC 3.3 - 5.0 V (powered via Bias Tee); **Maximum DC current:** 70 mA; **Frequency range:** 50 MHz - 4 GHz (according to the datasheet on PSA4-5043+); **Gain:** 25.4 dB, 50 MHz **/** 22.1 dB, 500 MHz **/** 18.4 dB, 1 GHz **/** 13.3 dB, 2 GHz **/** 10.2 dB, 3 GHz **/** 8.0 dB, 4 GHz; **Noise Figure:** 0.73 dB, 50 MHz **/** 0.65 dB, 500 MHz **/** 0.75 dB, 1 GHz **/** 0.98 dB, 2 GHz **/** 1.1 dB, 3 GHz **/** 1.44 dB, 4 GHz; **RF connector:** SMA; **Feed line:** 50 Ohm coaxial cable; [EasySDR project page at GitHub][1] Based on: [LNA4ALL Low Noise Amplifier][2] Buy SDR receiver: [RTL-SDR.COM][3] Buy PSA4-5043+ Low Noise MMIC Amplifier: [Mini-Circuits PSA4-5043+][4] Buy TCBT-14+ Bias Tee: [TCBT-14+][5] ## How to contact me? - E-mail: igor.nikolaevich.96@gmail.com - Telegram: https://t.me/igrikxd - LinkedIn: https://www.linkedin.com/ [1]: https://github.com/IgrikXD/Easy-SDR [2]: http://lna4all.blogspot.com/ [3]: https://www.rtl-sdr.com/shop/ [4]: https://www.minicircuits.com/WebStore/dashboard.html?model=PSA4-5043%2B [5]: https://www.minicircuits.com/WebStore/dashboard.html?model=TCBT-14%2B
