RF Toolbox

Defining RF Components

A key challenge in RF engineering is accounting for impedance difference and reflection effects that occur when components are configured into a network. RF Toolbox represents an RF component by its network parameters, which are sufficient to determine its small signal response. From the individual network parameters of a set of components, RF Toolbox can determine the network parameters and small signal response of any configuration containing these components.

RF Toolbox enables you to use network parameters to specify RF filters, transmission lines, amplifiers, and mixers, either directly or by their physical properties. Network parameters can be generated from within MATLAB or read in from external data. You can read and write industry-standard data file formats, such as Touchstone .snp. You can also specify components by their physical properties, such as RLC topology and values and transmission line properties. RF Toolbox calculates the corresponding network parameters.

Using RF Toolbox, you can define components in the following ways:

  • Passive networks and general circuit elements, using data from Touchstone .snp, .ynp, .znp, and .hnp files
  • Amplifiers and mixers, using data from Touchstone file formats (.s2p, .y2p, .z2p, and .h2p) and MathWorks file format (.amp)
  • Transmission lines, using the lines' geometries and electrical properties
  • LC ladder filters, using the filters' topology and values
