iSlipstick RF vs Smith Charts

iSlipstick RF iSlipstick RF contains all of the functionality of the standard iSlipstick plus many functions specifically for RF work. RF Calculators included with iSlipstick RF are: PATH LOSS – Enter all of the RF link parameters such as transmitter output power, antenna gain, cable loss, distance and frequency to find the actual RF level at the receiver. MICROWAVE DISH BEAMWIDTH & GAIN – Enter the dish size, frequency and efficiency to find the 3 dB beamwidth and antenna gain. WAVELENGTH – Metric & U.S. RETURN LOSS / VSWR – Enter forward and reflected power to find VSWR, reflection coefficient and return loss. FRESNEL ZONE – Enter link distance, obstacle distance and frequency to find the 60% and 80% zone radii. This calculator also provides a visual display of ground clearance. VELOCITY FACTOR (VOP) – Enter the dielectric constant of a coax to find the Velocity of Propagation and enter the cable length to find the propagation delay. This calculator can also find the necessary cable length for a given delay and VOP. INTERMODULATION – Enter up to six frequencies to find the 2nd, 3rd, 5th and 7th intermod products that can be created. A 'hit' window can be set to eliminate out of band results. I.F. FREQUENCY – Enter the incoming carrier frequency and 1st local oscillator frequency to find the resulting I.F. and whether the spectrum is inverted or normal. This is a great calculator when working with up/down converters. INTERCEPT POINT – Once you have determined the levels of fundamental and intermodulation tones in a system, you can enter those values into this calculator to find either IP2 or IP3. Standard Calculators included in iSlipstick RF are: OHM'S LAW – Find voltage, current, resistance and power. REACTANCE – Find inductive and capacitive reactance by entering frequency and capacitance or inductance. RESONANCE – Find the resonant frequency of an inductor – capacitor pair. VOLTAGE DIVIDER – Enter the voltage into a resistor divider network to find the output voltage. PARALLEL RESISTOR – Enter up to six resistor values to find the resultant parallel resistance. SERIES and PARALLEL RLC – Enter R, C and L of a series or parallel circuit to find the impedance and phase angle. OP-AMP – Find the gain of either an inverting or non-inverting op-amp circuit. TIME CONSTANT - Find the first 5 time constants of both RC and RL circuits. Standard Converters included in iSlipstick RF are: RESISTOR COLOR CODE – Enter a resistor value to find the color code or enter the color code to find the resistor value. SMD RESISTOR – Enter 3 digit or 4 digit SMD codes to find the resistance value. Also does EIA-96 conversion. VOLTAGE CONVERTER – Convert between RMS, average, peak and p-p values. dB CONVERTER – Convert dBm, dBV, dBW and dBuV to absolute values and vice-versa in 50, 75 and 600 ohm load. TEMPERATURE – Convert between four popular scales. PERIOD – FREQUENCY – Convert waveform period to frequency and vice-versa. LENGTH, AREA, VOLUME, CAPACITY and WEIGHT – Convert from metric to U.S. and vice-versa. Also convert within same standard. A help page is also available as a quick function guide. Tested with iOS 12.0 thru iOS 15.1

A great experience of the Smith chart. Also in dark mode. Design matching networks, insert S parameters and convert them, or import from touchstone file. Compute stability circles, equi gain and noise circles.  Easy interaction with the Smith chart. This chart can easily replace a physical one, making its use much faster. Smith chart interactivity: - Works on iPhone, iPad and Mac (on Apple Silicon). - Drag and zoom in the chart. - Create multiple Smith Charts and name them. - Switch easily between input and output planes. - Use a ruler and drag it to obtain the wavelength toward generator of a point on the chart, instantly. - Tap the chart to show the coordinates in algebraic notation, you will see also magnitude and phase of that location, and the corresponding impedance. - Insert circles by hand; modify the radius dragging a circle to keep the center in place, or press to translate them and modify the radius keeping the opposite side in place. Then use the padlock button to disable interaction of gestures with circles. - You can also insert a custom circle and a segment in the input and in the output plane, defining its center and radius in a textfield. - Export to file, image or PDF Advanced tools for engineering: Matching networks: - Choose electronic components to design a matching network for your device. - Available components are: L, C, R, Z and lines (transmission line, parallel or series stub, open or shorted). - For each component it is possible to specify the parasites. - For transmission lines, it is possible to choose between Z0, K or L, C representations, and converting between the two (also for parasites). - Tapping on a component it is added to the network and the impedance seen from your device toward the matching network is shown on the smith chart. - You can create a matching network both for input and output planes of the device. - Each network has its own termination (source or load), which can be a one port device or a two ports device where you can choose a termination for the second port. - Each termination can be defined by network parameters (S, Z, Y or h) and the parameters can be imported from a touchstone file. - Components supported: Resistor, Capacitor, Inductor, General impedance (R+jX), Transmission line, Parallel stub, series Stub (both shorted or open). - Each component can be cascaded in series or in parallel, no limits of components. - You can choose a frequency for the impedance calculation and a frequency span for the plot on the Smith Chart. - For S parameters, you can specify a dedicated characteristic impedance, the tool will renormalize the Γ of that termination to be correctly shown on the Smith chart, when the smith chart is defined on a different characteristic impedance. Device analysis: - You can insert the following parameters of a device: network parameters (S, Z, Y or h), specifications (Ga, Gp, Gt, NF), noise data (gamma s optimum noise, minimum NF, rn) and the input/output reflection coefficients. - You can convert network parameters (S, Z, Y, h), and the port type (Γ, Z, Y). - While you are inserting data, you will see the computed results appearing on the chart and on the relative fields. - Results representable on the smith chart: input/output stability circles, power gain and noise circles (equiGa, Gp, Gt, NF circles), reflection coefficients towards load and source and optimum power coefficients. - Other results: obtained power gains and noise (Ga, Gp, Gt, NF) and stability (D, K, kind of stability). - You can display on the Smith chart the input impedance of your component versus frequency (as a function of load impedance) when importing a touchstone file. - For S parameters, you can specify a different characteristic impedance and the tool will automatically convert it to the one defined for the Smith chart, it will let you know the new renormalized parameters.
