United StatesSpecialized 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 ■ ASCII Table ■ Desktop calculator ■ Resistor/Capacitor/Inductor combinations tool ■ 4-20mA conversion tool ■ Passive cooling calculator ■ Audio Oscilloscope Please check out more screen shots on my website (WEBSITE Link on the left side).

A most excellent App
Mr. Roskosch’s ETB Is A “Killer App”... Professional, Intuitive Expansive And Kept Up To Date! I Highly Recommend This App For All Good People... 73 KS4ML
United StatesGreat app
This is just a great app!
United StatesVery Handy
This is just a fabulous app for anyone working with RF. Especially handy when designing equipment at the component level and almost everything you need is all in one app.
United StatesA real electronic toolbox
What a nice professional product. I use this app weekly, saves time from not getting on a workstation just to design or validate a simple circuit. Both RF-Toolbox Pro and Electronic TB Pro have been excellent references, and are always being improved/updated by Marcus. Thank you.
United StatesElectronics 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. Jim
United StatesMarcus Strikes Again
Like the rest of his apps this is also great!
United StatesVery good application
I have been in electronics as a technician, engineer, and ham radio operator for over 50 years. This is the best program of its kind considering the price.
