RF Path Analysis Toolkit 1.4 Released!

We just released an update to RF Path Analysis Toolkit (Version 1.4). The release contains some nice time saving features and improvements:

  • Drag and Drop RF Components: In the RF Path Builder display, you can now drag and drop RF components in the path table rows. This makes it easy to move RF components around in the RF path. Previously if you wanted to move an RF component, you had to delete the RF component, and then look it up again in the library to insert it into a new location.
  • Sub paths: You can now define an RF Path as a series of sub paths, which are individual RF path files. This saves potential errors and time in updating many RF paths containing the same path information. Previously, you could only manually load sub paths into an RF path file. Now they can be defined within the RF path file itself.
  • Export to Excel options: Now you can select the option to leave the detailed RF path analysis spreadsheet open after "Export to Excel" is selected. Previously the detailed RF path analysis spreadsheet was closed after "Export to Excel". This is convenient for viewing the detailed results quickly as you are building RF paths.
  • More information in the RF Path Builder display: As you are building an RF path in the RF Path Builder, you can now see the following parameters:
    • Device Nominal Gain
    • Cumulative Gain to Device Output
    • Device Noise Figure
    • Cumulative Noise Figure to Device Output
    • Signal 1 Power at Device Output
    • Signal 2 Power at Device Output
    • Device Third Order Output Intercept Point
    • Cumulative Third Order Input Intercept Point
    • Device 1 dB Output Compression Point
    • Signal 2 Delta from Device 1 dB Compression Point
    • Third Order Spurs at Device Output (new!)
    • Cumulative 1 dB Input Compression Point (new!)
    These new parameters are helpful when designing RF paths with difficult dynamic range requirements, and provide more insight into dynamic range contributors as you are building the RF path.
  • Path File Save and Load folders: You can now specify the default directory for saving and loading RF path files. Previously this was fixed to the "Level 1" directory.
  • Revised template spreadsheets: We've updated and improved the template detailed analysis spreadsheets. There are now two template spreadsheets:
    • RFPATTemplate4-2.xls is a simplified (but still very useful) RF path analysis spreadsheets for receivers and transmitters. Antenna gains can not be accurately incorporated into the model. Sensitivity calculations are based on the receiver RF components only.
    • RFPATTemplate6-2.xls is a more advanced RF path analysis spreadsheet. This template allows for separate RF component "signal gain" and "noise gain" parameters. This allows the spreadsheet to show radiated sensitivity, because antenna gains can be taken into account (antennas have "signal gain" but no "noise gain"). Basic RF components have the same "signal gain" and "noise gain".
  • File Path dialog boxes should be more descriptive and helpful.
  • Other changes to the user interface/display to help clarify the operation of the program.
Upgrades are free to previously registered users. Download the new version (, give it a try, and let us know what you think!
