RF toolbox: Electronics

A collection of tools that helps electronics/RF engineer and hobbyist design radio frequency systems and electronics filter circuits

RF Toolbox — All-in-One RF Engineering Calculator & Design Suite

RF Toolbox is a practical, field-ready app built for RF engineers, students, and radio hobbyists who need fast, reliable calculations and design utilities in one place. From impedance matching and transmission line work to filter and attenuator synthesis, RF Toolbox helps you move from idea to implementation with less friction.

KEY FEATURES

Impedance & S-Parameter Tools • Smith Chart utilities for impedance visualization and matching workflows • S11 parameter / reflection analysis support • Reflection coefficient and VSWR calculators

Matching Networks • L, Pi (π), and T matching network calculators • Stub tuner tools for transmission-line matching

• Filters (Passive & RF) • RC and RL passive filter calculators • LC low-pass prototypes: Butterworth and Chebyshev (up to 8th order) • Microstrip filters: band-pass and band-reject (notch)

• RLC Networks • RLC series and parallel calculators for resonance and frequency behavior

Attenuators • Pi (π), T, and Bridge-T attenuator calculators for common RF pad designs

• Cascaded Networks • Cascaded network calculations for chained RF blocks and stages

Antenna & Propagation • Antenna design utilities (core RF design helpers) • Path loss calculators • Friis link budget calculator • Power density calculator • Radar maximum range calculator

Component Toolkits • Inductor design: air-core, spiral, and multi-layer air-core • Resistors: SMD code, color code, and series/parallel network calculator • Capacitors: SMD code and series/parallel network calculator

DESIGNED FOR SPEED AND ACCURACY RF Toolbox is organized for quick access—open the tool you need, enter values, and get results immediately. Whether you’re prototyping a matching network, checking VSWR, sizing an attenuator, or running a quick link budget, RF Toolbox keeps your workflow efficient.
