Description
EasyEDA project for easy and quick build "LNA, Bias Tee powered" module for amplify weak radio signals without significantly increasing the noise level and compensation for loss of useful signal when passing through a coaxial cable. Project includes schematic and PCB prepared for setting up into aluminum enclosure with dimensions 50 x 25 x 25 mm with N-Type connectors. Version for mounting SMD components. ## Current development progress: [![Progress](https://img.shields.io/badge/LNA,%20Bias%20Tee%20powered%20%28SMD,%20ENCLOSURE%29-tested-green.svg)](https://github.com/IgrikXD/Easy-SDR) [![Progress](https://img.shields.io/badge/version-1.0.EE-blue.svg)](https://github.com/IgrikXD/Easy-SDR) [![Bug report](https://img.shields.io/badge/Google%20Form-Create%20bug%20report-red.svg)](https://docs.google.com/forms/d/e/1FAIpQLSeUFM1p15N_vk8X_blSnZp6jPlZe_qRhiRlmntscx6jF2yRqw/viewform?usp=sf_link) **Input voltage:** DC 3.3 - 5.0 V (powered via Bias Tee); **Maximum DC current:** 76 mA (PSA4-5043+), 200 mA (PGA-103+); **Frequency range:** 50 MHz - 4 GHz (according to the datasheet on PSA4-5043+ and PGA-103+, upper frequency may be unattainable with FR-4 PCB material); **Gain characteristics table (+5 V supply voltage):** | Frequency | PSA4-5043+ | PGA-103+ | | ----------------- | ---------- | -------- | | 50 MHz | 25.4 dB | 26.5 dB | | 400 MHz | 22.1 dB | 22.1 dB | | 1 GHz | 18.4 dB | 16.2 dB | | 2 GHz | 13.3 dB | 11.0 dB | | 3 GHz | 10.2 dB | 8.1 dB | | 4 GHz | 8.0 dB | 6.2 dB | **Noise Figure characteristics table (+5 V supply voltage):** | Frequency | PSA4-5043+ | PGA-103+ | | ----------------- | ---------- | -------- | | 50 MHz | 0.73 dB | 0.5 dB | | 400 MHz | 0.65 dB | 0.5 dB | | 1 GHz | 0.75 dB | 0.6 dB | | 2 GHz | 0.98 dB | 0.9 dB | | 3 GHz | 1.1 dB | 1.2 dB | | 4 GHz | 1.44 dB | 1.5 dB | **Output IP3 characteristics table (+5 V supply voltage):** | Frequency | PSA4-5043+ | PGA-103+ | | ----------------- | ---------- | -------- | | 50 MHz | 31 dBm | 36.7 dBm | | 400 MHz | 32.1 dBm | 39 dBm | | 1 GHz | 33.5 dBm | 41.9 dBm | | 2 GHz | 32.7 dBm | 44.6 dBm | | 3 GHz | 33.6 dBm | 44.3 dBm | | 4 GHz | 32.6 dBm | 45.4 dBm | **RF connector:** N-Type; **Feed line:** 50 Ohm coaxial cable; **Used PCB Material:** FR-4; **PCB thickness:** 1.6 mm; **PCB copper weight:** 1 oz; [EasySDR project page at GitHub][1] Buy SDR receiver: [RTL-SDR.COM][2] Buy PSA4-5043+ Low Noise Amplifier: [Mini-Circuits PSA4-5043+][3] Buy PGA-103+ Low Noise Amplifier: [Mini-Circuits PGA-103+][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://www.rtl-sdr.com/shop/ [3]: https://www.minicircuits.com/WebStore/dashboard.html?model=PSA4-5043%2B [4]: https://www.minicircuits.com/WebStore/dashboard.html?model=PGA-103%2B [5]: https://www.pcbway.com/QuickOrderOnline.aspx
