How does the RF impedance matching calculator work?

RF Impedance Matching Calculator. Calculates the network to match a line to a specific complex load. This tool calculates the matching network necessary to terminate a line of the specified characteristic impedence (Z o) in a specific complex load impedence (R L + jX L) at a specified frequency. It supports both balanced and unbalanced lines.

How to do a load impedance calculator?

This tool allows for three ways of specifying the complex load impedance. The user can specify the real and imaginary impedence directly, or supply R and C values or S parameters (magnitude and phase). Results are displayed only when all of the input parameters have been provided.

How are via impedances similar to trace impedance?

Indeed, vias behave a bit like traces – albeit in the Z dimension. Figure 1 shows stripline trace impedance versus width, spacing, and distance from ground planes (X axis represents W=S=H1=H2 per the cross-section view).

How to determine the impedance of a network?

The tool provides two networks that will have the desired impedence at that frequency, but their behavior will differ at frequencies above and below the frequency specified, so you may prefer one over the other, depending upon your application. This tool allows for three ways of specifying the complex load impedance.

How to calculate the impedance of an amplifier?

To use the calculator, enter in the amp’s S-parameters.The characteristic impedance used in the S-parameter measurements. The frequency at which you will use the amplifier, the source’s and load’s impedance, and whether you want high pass or low pas networks on the L-Matching networks.

What are the parameters of an RF amplifier?

The frequency at which you will use the amplifier, the source’s and load’s impedance, and whether you want high pass or low pas networks on the L-Matching networks. Remember that the S-parameters are a function of how the amplifier is biased.

How to calculate the stability of an amplifier?

Given a amplifier or transistor’s the S-parameters (scattering parameters), this calculator will analyze its stability, maximum gain, an even suggest a suitable conjugate L-matching network for a given load and source impedance of the circuit to which the amplifier will be connected.
