iCircuit vs RF

iCircuit is the premier iPhone and iPad app for designing, simulating, and learning analog and digital electronics. Its advanced simulation engine provides real-time, always-on analysis so your circuits stay powered and live, just like working with real components. Use it like a CAD tool: add components, wire them up, and set their properties. But iCircuit is unlike typical CAD apps because it is always simulating. You do not stop to take a measurement or spend time configuring reports. Instead, you just play with the circuit as you normally would, with the power on. Build circuits with over 300 components, from simple resistors and LEDs to programmable Arduinos (Uno, Nano, Mega, ESP8266, ESP32), Raspberry Pi Pico boards running real MicroPython and CircuitPython, PIC microcontrollers, and 60 4000/7400-series digital ICs (more available with Pro). Connect elements, adjust values, and instantly see the results. BUILT-IN TEST EQUIPMENT • Multimeter: Probe any point to read voltage, current, and power • Oscilloscope: Track multiple signals with touch-controlled time scale, stacked/unstacked views, FFT analysis, and Bode plots • Gauges: Visualize voltages, currents, and frequencies directly in your circuit • Signal generators and configurable sources EXTENSIVE COMPONENT LIBRARY • Raspberry Pi Pico and Pico 2 running genuine MicroPython and CircuitPython firmware • Programmable Arduinos (Uno, Nano, Mega, ESP8266, ESP32) • Programmable PIC microcontrollers (assembly and HEX files, more available with Pro) • Power: Voltage regulators (78xx, LM317), sources, dependent sources, power jacks, and simulated antennas • Analog: Resistors, capacitors, inductors, diodes, BJTs, MOSFETs, thermistors, triodes, and tetrodes • Digital: Logic gates (AND, OR, NAND, NOR, XOR), JK and D flip-flops, and 60 4000/7400-series ICs (180+ available with Pro) • ADCs and DACs • Sensors and displays: LEDs, 7-segment, NeoPixels, matrix displays, thermistors • Electromechanical: Motors, servos, SPST/SPDT and DPST/DPDT switches, push buttons, relays, and speakers SPICE, VERILOG, AND VHDL Import vendor SPICE models and subcircuits and use them as components. Write Verilog or VHDL in the HDL element and wire it to the rest of your circuit. CREATE CUSTOM ELEMENTS Build sub-circuits and custom elements to componentize your designs and create reusable modules. Share your custom elements with others via the iCircuit Gallery. AUDIO SIMULATION Hear your circuits. Speakers, buzzers, and microphones produce real audio output. Perfect for students learning electronics, hobbyists prototyping projects, and engineers validating designs, all without burning out a single component. ABOUT ICIRCUIT PRO (OPTIONAL) iCircuit is a complete app with a one-time purchase. iCircuit Pro is optional and adds extra components (including more PICs and a larger 4000/7400 IC library) and helps fund ongoing development. Pro is not required for core simulation or everyday circuit design. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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).
