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 ■ 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).

The app is used in the industrial pipe construction. (American Standard ASME B36.10/ B16.9) Functions: Calculation (imperial and metric) of offsets and weight calculation of pipes, offsets and profiles. All nominal diameter and fittings are provided, so it will be very easy for you to solve complex calculations quickly. Even if you put in false information, you can not get wrong solutions. This way you can save material, time and stress. The App is your help in a hectic and busy working day. - 28 offset calculations (8 offset types with 2 or 4 interrupts) - Given nominal diameters (NPS 1-40/DN 25-1000) according to ANSI/ASME with outside diameter (exemple NPS 5/DN 100- 4.5in/114,3mm), - Calculation with lenght or elbow angle - 2 types of elbow - Manual input of elbow radius - Offsets with tee - Individual gap - Detailed help and description - History of your calculations Results - Cut length - Elbow angle - Inside and outside cutting values of the elbow - Take off, chord - Installation length of offset - Calculation of offset weight Weight calculation of - Pipes, - 2 types of elbow - Channels (C3-C10) - H Beams (W4-W10), - Manual inputs. Single weights will be added to the list, so that you can use the weight of the construction units to choose the right lifting gear.
