Specialized on high frequency electronics for RF professionals, radio amateurs and students.
RF-Toolbox is based on the popular Electronic Toolbox from Marcus Roskosch.
This app contains some of the common tools from 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 totally 79 tools and like with Electronic Toolbox, there are more to come over the time.
■ PCB Trace Width (Internal and external Traces)
■ PCB Trace Resistance
■ PCB Trace Impedance (various trace types e.g. Microstrip, embedded Microstrip, Symetric 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...

Electronics and RF Tools
WOW....... After a 30 year break I decided to get back into Ham Radio and Electronics I stated in Boy scouts. Needless to say my math skills were never great and now pretty much gone, my military service took its toll.
A few years ago I looked for this type of software but nothing like these were available, but tonight I found these two sets of tools and about hit the floor when I opened them, for me and others without an EE degree these tools include everything I need to not only troubleshoot equipment but now I think I’ll be able to build my own.
I cannot say enough good things about these, check them out you won’t be sorry. Now if someone could develop programming tools for ATMELs and PICs I’ll be in heaven.
Thank you for developing these awesome apps.
Second to none
I'm a lifetime electronics technician and can testify this is what gets you going in the right direction for most of your formula needs. I appreciate that the developer continues to support the app for well over a year since I bought it. Bugs squashed before I knew it was a problem.
This app is a breath of fresh air! Every time I'm in the middle of a project & I'm stumped, this app comes to the rescue. Unlike the ARRL handbook there is no wasted, high minded verbiage to sift through. Answers come quickly! Well thought out. Love it
