Noise Figure Analyser Kit with Arduino Mega
Noise Figure Analyser Kit with Arduino Mega – Transform Readings into Professional RF Instrumentation
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You’ll build a fully functional noise figure analyser—an instrument that quantifies how much noise your low-noise amplifier adds to a signal. Using the classic Y-factor method with a calibrated LM388 noise source and dual ADS1115 high-precision ADCs, this kit transforms an Arduino Mega into a professional-grade RF measurement tool. Perfect for characterising LNAs in satellite receivers, IoT gateways, and radio astronomy front-ends.
What You'll Build
A desktop instrument with a 1.8-inch TFT colour display showing measured noise figure in dB, gain, and equivalent noise temperature. The system captures cold and hot noise power levels via a multiplexed I2C architecture, automatically computing the Y-factor and NF with sub-0.1 dB repeatability. Once assembled, you’ll have a lab-grade analyser that belongs on any serious RF electronics bench.
What You'll Learn
- Implement the Y-factor method for precise noise figure measurement
- Interface multiple I2C devices using a TCA9548A multiplexer for noise floor isolation
- Capture and process microvolt-level noise signals with ADS1115 16-bit ADCs
- Design and solder a multi-board prototype system for stable RF measurements

Who This Kit Is For
Ideal for B.Tech ECE/EEE students undertaking microwave and RF design projects, Smart India Hackathon teams characterising LNAs for IoT sensor networks, and final-year IIT/NIT/VIT/BITS capstone scholars needing a dedicated NF measurement setup. ATL tinkering lab mentors can also lead advanced workshops on RF instrumentation using this kit.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to launch our AI build companion, which walks you through each calibration step. You also have live WhatsApp backup for real-time troubleshooting with our team.
Do I need prior RF experience to build this kit?
Familiarity with basic electronics and RF concepts like noise temperature is helpful, but the AI companion explains every measurement step and guides you through the Y-factor calibration, making it accessible even if you’re new to RF instrumentation.
Can I use this analyser to characterise LNAs for different frequency bands?
Yes, the LM388 noise source covers 10 MHz to 2 GHz, and the measurement technique is frequency-agnostic. You can adapt the setup for any LNA within that range by following the companion's guidance on impedance matching and connectorisation.
Is the included soldering iron suitable for the PCB prototype boards?
The kit’s iron is optimised for through-hole soldering on the supplied protoboards. For SMD components or future fine-pitch work, you may wish to upgrade, but everything needed for this build is fully compatible.
LNA under test driven by noise source. ADS1115 measures output noise with and without LNA to compute NF.
