System Frequency Domain Analysis: Receiver Circuit

This example shows System Frequency Domain (FD) analysis of a receiver circuit consisting of Nexxim filters and transmission lines combined with Nexsys behavioral MIXER and AMP elements.

The schematic and data file for the example are available in the Examples directory.

Open the project on the Examples directory.

  1. From the File menu, select Open Examples to open an explorer window.
  2. Open the Electronics Desktop directory, then Circuit, then RF_Microwave, the System directory, then select the file System_FD_Receiver_Example.aedt. Click Open.
  3. The Examples directory is write-protected. Use File>Save As to save the example project to a directory where you have write permission. A Handle Project Directory Files window opens showing you the supporting model files that is copied along with the project. Click OK.
  4. The schematic opens in the design window.

The central transmission line TRLK component is 240 inches (20 feet) in length. The AMP elements on the transmitter and receiver ends of the long TRLK use NMF files for the compression data. The other AMP elements and the MIXER elements have S-parameters specified as component properties.

  1. Expand the Analysis folder, right-click and select Analyze (you may need to use Force Analysis).
  2. When the analysis is complete, expand the Results folder and click the pout report to see the spectral distribution of the output power.
