Description
EasyEDA project for easy and quick build "RF power limiter" module used to protect the receiving equipment from too strong input signals (by limiting the output level) that can damage it. Project includes schematic and PCB prepared for setting up into aluminum enclosure with dimensions 50 x 25 x 25 mm with SMA connectors. Version for mounting SMD components. ## Current development progress: [![Progress](https://img.shields.io/badge/RF%20power%20limiter%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) **Frequency range:** 30 MHz - 3 GHz (according to the datasheet on RLM-33+, upper frequency may be unattainable with FR-4 PCB material), 3 MHz - 750 MHz (according to the datasheet on RLM-751-2WL+); **Linear range insertion loss:** 0.23 dB (RLM-33+), 0.2 dB (RLM-751-2WL+); **Linear range max input power:** 5 dBm (RLM-33+), -10 dBm (RLM-751-2WL+); **Limiting range output power:** +11.5 dBm (RLM-33+), +8.0 dBm (RLM-751-2WL+); **Limiting range input power:** +12 - +30 dBm (RLM-33+), +5 - +33 dBm (RLM-751-2WL+); **RF connector:** SMA; **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 RLM-33+ Limiter: [Mini-Circuits RLM-33+][3] Buy RLM-751-2WL+ Limiter: [Mini-Circuits RLM-751-2WL+][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=RLM-33%2B [4]: https://www.minicircuits.com/WebStore/dashboard.html?model=RLM-751-2WL%2B [5]: https://www.pcbway.com/QuickOrderOnline.aspx
