Inport

Convert Simulink input signal to SimRF signal

  • Library:
  • SimRF / Circuit Envelope / Utilities

Description

The Inport block imports Simulink® signals into the SimRF™ circuit envelope simulation environment. For an introduction to RF simulation, see the example, Simulate High Frequency Components.

Complex-valued input signals Ik(t) + j · Qk(t) are the modulations at the frequencies {fk} specified in the Carrier frequencies parameter of the block.

The Source type parameter specifies the Simulink signal as either current, or voltage, or power source.

Parameters

expand all

Inport block interpretation of Simulink signal, specified as:

  • Ideal voltage — The block outputs Simulink signals as voltage signals v(t) in the SimRF environment. When you choose this option, the following figure illustrates the internal configuration of the block.

  • Ideal current — The block outputs Simulink signals as current signals i(t) in the SimRF environment. When you choose this option, the following figure illustrates the internal configuration of the block.

  • Power — The block interprets the Simulink signals, Pv(t), as available power and internally uses a voltage source, and series impedance as shown in the following figure.

    The voltage v(t) is a scaling of the Simulink signal vSL(t):

    v(t)=2Re(Zs)vSL(t)

    In the preceding equation, Zs is the value of the Source impedance (ohms) parameter.

    The generator delivers real power to the load Zl:

    Pload=|v(t)|2Re(Zs)|Zs+Zl|2

    When Zl = Zs*, this generator delivers the available power |vSL(t)|2.

Fundamental tones of a set of simulation frequencies, specified as a vector of positive integers in ohms.

Dependencies

To enable this parameter, select Power in Source type.

Carrier frequencies, specified as a vector of positive integers in Hz. In carrier frequencies, the elements are a combination of fundamental tones and corresponding harmonics in the Configuration block.

Select this parameter to ground and hide the negative terminals. Clear the parameter to expose the negative terminals. By exposing these terminals, you can connect them to other parts of your model.

By default, this option is selected.
