Featuring a universal RP-SMA interface and powered by a mini USB 5V supply, this compact, copper-based PCB module ensures reliable, precise RF power control for professional-grade instrumentation. ## Description Product description Specification Operating Frequency Range: 1 ~ 3800MHz Input Maximum Power: 20dBm Attenuation Range and Step: Attenuation range from 0~31dB, step size is 1dB Insertion Loss: Less than 2.0dB Attenuation Control: Press OK key, press + after the attenuation digit blinks, - key to control actual addition or subtraction, press OK again to confirm Input Output Impedance: 50Ω Power Supply: MiniUSB 5V Input Output Interface: RP SMA interface Package List: 1 x RF Programmable Attenuator 1 x USB Cable Review: Pretty decent up to 6GHz - The 0 dB step at 6GHz is -2 5dB. Which is to be expected. Then from there it's very close to 1dB per 1dB attention. Review: Buy something different if your circuit may have power possibly interrupted. - Requires constant voltage to maintain input setting. Okay if input power is backed up but loss of voltage means this one and any others have to be reset. I had plans to use five (5) on different circuits. Looks like I'll be looking for way to provide 5vdc all the time. ## Features - WIDE APPLICABLE: Variable RF attenuator use universal RP SMA interface, suitable for a variety of instruments - FREQUENCY AND : The maximum working frequency range of RF attenuator is 1MHZ‑3800MHz, and the maximum power of input is 20dBm - IMPEDANCE AND POWER SUPPLY: The input and output impedance of digital RF attenuator module is 50Ω, and the power supply adopt mini USB 5V - ATTENUATION RANGE AND STEP SIZE: The RF programmable attenuator has a attenuation range of 0 to 31dB and a step size of 1dB - PCB: Digital RF attenuator module adopts excellent PCB material, with high reliability and miniaturization, good maintenance and interchangeability ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Eujgoov | | Part Number | Eujgoovogzt0bxeus | | Item Weight | 2.72 ounces | | Package Dimensions | 3.94 x 3.94 x 1.18 inches | | Item model number | Eujgoovogzt0bxeus | | Material | copper | | Batteries Included? | No | | Batteries Required? | No | ## Images ![RF Attenuator Module 0‑31dB Adjustable Programmable Attenuator Board Digital RF Power Attenuation Module - Image 1](https://m.media-amazon.com/images/I/71Iaa60PJqL.jpg) ![RF Attenuator Module 0‑31dB Adjustable Programmable Attenuator Board Digital RF Power Attenuation Module - Image 2](https://m.media-amazon.com/images/I/71sEKR-vD1L.jpg) ![RF Attenuator Module 0‑31dB Adjustable Programmable Attenuator Board Digital RF Power Attenuation Module - Image 3](https://m.media-amazon.com/images/I/71k7rtBHyML.jpg) ![RF Attenuator Module 0‑31dB Adjustable Programmable Attenuator Board Digital RF Power Attenuation Module - Image 4](https://m.media-amazon.com/images/I/81lfp3j3iCL.jpg) ![RF Attenuator Module 0‑31dB Adjustable Programmable Attenuator Board Digital RF Power Attenuation Module - Image 5](https://m.media-amazon.com/images/I/71veD99fXtL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pretty decent up to 6GHz *by M***N on May 13, 2024* The 0 dB step at 6GHz is -2 5dB. Which is to be expected. Then from there it's very close to 1dB per 1dB attention. ### ⭐ Buy something different if your circuit may have power possibly interrupted. *by J***N on December 12, 2025* Requires constant voltage to maintain input setting. Okay if input power is backed up but loss of voltage means this one and any others have to be reset. I had plans to use five (5) on different circuits. Looks like I'll be looking for way to provide 5vdc all the time. ### ⭐ Received was defective *by J***. on October 31, 2023* I received this device not working properly and tried to get a replacement. I did not receive the replacement package as it was held up somehow in transit. I think Amazon will resolve the issue. ## Frequently Bought Together - RF Attenuator Module 0‑31dB Adjustable Programmable Attenuator Board Digital RF Power Attenuation Module - SDTC Tech 5pcs Coaxial Coax Cable Assembly SMA Male to SMA Male Antenna Extender Cable Adapter Jumper(6 inch/15cm) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/553264665-rf-attenuator-module-0-31db-adjustable-programmable-attenuator-board-digital](https://www.desertcart.in/products/553264665-rf-attenuator-module-0-31db-adjustable-programmable-attenuator-board-digital) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-24*
