RF Calculator & Smith Chart

Electronics Toolbox: RF is the ultimate all-in-one RF calculator and microwave engineering suite. Designed for hardware engineers, radio technicians, and students, this app streamlines complex calculations for wireless communication and circuit design.

From impedance matching with an interactive Smith Chart to calculating link budgets and path loss, this app replaces dozens of spreadsheets with a single, high-precision mobile utility.

Here is a more ASO-focused version for Play Store, while still sounding natural:

RF Engineer Toolkit – RF, Microwave & Antenna Calculator

RF Engineer Toolkit is a powerful RF and microwave calculator app for engineers, students, technicians, ham radio operators, and wireless professionals. It brings together essential radio frequency design, transmission line, antenna, impedance matching, and filter tools in one easy-to-use app.

Core RF & Microwave Tools

System Analysis
Calculate link budget, EIRP, Friis transmission, radar maximum range, and path loss. Includes popular path loss models such as FSPL and Hata for wireless and network planning.

Impedance & VSWR
Convert VSWR, return loss, reflection coefficient, and S11 quickly. Use stub tuner and quarter-wave transformer tools for RF impedance matching.

Filter Design
Design Butterworth, Chebyshev, and RLC filters with ease. Visualize circuit response using built-in Bode plot tools.

Antenna Design
Design Yagi-Uda arrays and microstrip patch antennas. Calculate antenna gain, beamwidth, and other important antenna parameters.

Transmission Lines
Use precise calculators for coax cable, microstrip, rectangular waveguide, and cylindrical waveguide analysis.

Circuit Analysis
Work with Pi attenuator, T attenuator, cascaded noise figure, skin depth, and series or parallel RLC resonance calculations.

Component & Passive Tools

SMD Codes
Identify SMD resistor and capacitor values instantly.

Inductor Design
Calculate air-core, toroid, multilayer, and spiral inductors for RF and electronics projects.

Conversions
Convert power to dBm, frequency to wavelength, and calculate inductive and capacitive reactance (XL, XC).
