RF StateSide Engineering Tools

Free, browser-based calculators and design helpers from RF StateSide, LLC – including the new Attenuator Pad Designer and the upcoming Network Matching Tool for impedance-transforming L, Pi, and T networks.

Built by Ray Faucher, KB1SO

HF amplifiers • Couplers • NMEA 2000 • Embedded control

Available Tools

Use these tools to explore coupler behavior, detector scaling, and ADC interface details. New tools will be added over time as RF StateSide projects grow.

Forward Sampler Calculator

Models the RF current transformer, forward sampler node, detector, MCU ADC voltage, and RF sampler port dB down from the main line.

50 Ω line • 1:N CT • RF + DC outputs

Open Forward Sampler Tool →

Attenuator Pad Designer

Compute resistor values and power dissipation for classic T-pad and π-pad attenuators in 50 Ω and other systems.

Updated with resistor wattage calculations & safety margin.

Network Matching Tool

Calculates L-network, Pi-network, and T-network matching components for impedance transformation, including power handling estimates.

In development
