Specialized on high frequency electronics for RF professionals, radio amateurs and students.

RF-Toolbox is based on the popular Electronic Toolbox by Marcus Roskosch.

This app contains some of the common tools of Electronic Toolbox but contains a wide range of additional tools, specialized for high frequency electronics, RF professionals, radio amateurs and students.

Currently RF-Toolbox consists of more than 90 tools and like Electronic Toolbox, there are more to come over the time.

Feature list:

■ PCB Trace Width (Internal and external Traces)
■ PCB Trace Resistance
■ PCB Trace Impedance (various trace types e.g. Microstrip, embedded Microstrip, Symmetric and Asymetric Stripline, Wire Microchip, Wire Stripline, Edge Coupled Microstrip and Stripline)
PCB Crosstalk (Microstrip and Stripline)
■ LC L/T/Pi Match calculation
■ Coax Cable calculation (Standard and individual Types)
■ Amplifier and Attenuator cascade calculation
■ SWR / Reflection / Return loss conversion
■ Power Divider (Branchline, Ratrace and Wilkinson)
■ Capacitor Plate calculation
■ RLC Parallel, Series and Circuit calculation
■ Noise Figure conversion
■ Skin Depth calculation (various materials from Aluminum to Silver)
■ Butterworth Filter (also with plot of filter chart)
■ Chebyshev Filter (also with plot of filter chart)
■ R-C, L-C, R-L High/Low/Band-Pass Filter
■ RF Units conversion (quick conversion of frequently used units)
■ Air coil inductance calculation
■ Resistors, Capacitors, Inductors in Parallel / Series
And there is much more...
■ Aktive Filter calculation tool
■ Antenna calculation tool
■ Delta Star calculation
■ Cable length / ampacity tool
■ PTC / NTC Temperature Resistance conversion
■ AC Ohms law tool
■ Zener diode circuit calculation
■ Constant current source tool
