RF Workbench™  -- RF Cascade Analysis

Download RF WorkbenchDownload RF WorkbenchClick an icon to download RF Workbench only after you have read and agreed to the Shareware terms.

NOTE: If you have either Microsoft Excel, then you might be better off using RF Cascade Workbook for the cascade calculations and the filter responses. The results are the same, but the convenient spreadsheet format allows you to use an infinite number or stages all in one file. It does not, however, have the Spur Web feature for calculating mixer spurious products - for that, use RF Workbench.

System Requirements:   80386, 2 MB RAM, 1 MB Hard Disk, VGA Color Monitor, Mouse

Note: RF Workbench WILL NOT run in any 64-bit version of Windows w/o an emulator! Fortunately, DOSBox (free) will allow a DOS screen capture of any RF Workbench screen! It also fixes "The NTVDM CPU has encountered an illegal instruction," errors.

When unzipping "rfwb40b.zip", be sure to select the option to re-create the subdirectories.;

Component Models
  • Gain Blocks: Gain/Loss, NF, IP2, IP3, P1dB, TC.
  • Mixers: Conv Loss/Gain, NF, IP2, IP3, P1dB, TC, LO Pwr, RF Pwr, Single-Tone 9x9 Spur Table (loadable from file).
  • Filters: fC, BW, fU, fL, N, IL/Gain, Ripple, NF, IP2, IP3, P1dB, TC; {Ideal, Butter, Cheby, Bessel}. Calculates effective noise BW. Calculates 3dB BW for Cheby.
  • Input: Linear sweep or data file.
  • LO: Fund Pwr, 2nd Harm Pwr, fC, BW, fU, fL, Fixed/Tracking.
Graph Screen
  • Plots of amplitude and group delay versus frequency.
  • Dynamic cursor readout.
  • Absolute and relative cursor readout modes.
  • Auto or manual scaling of axis limits.
  • Scale zoom with mouse.
  • Customize plot colors and which plots to view.
  • View a table of calculated values in a window.
Spur Web Screen
  • Unique graphical search method for simple frequency plan determination.
  • Tracking and fixed LO models accommodated.
  • Specify harmonic range to search.
  • Customize in-band and out-of-band colors.
  • In-band spur products listed in table with labels placed on plot.
  • Open spur level calculation window for exact frequency and amplitude.
Planning Screen
  • Up to five stages on one screen.
  • 3-dimensional frequency plan graph with dynamic cursor readout.
  • Two modes: (1) You enter stage parameters and let RF Workbench calculate input/output results or (2) You enter the stage inputs/outputs and let RF Workbench calculate the worst case requirements for each stage that will ensure meeting system specifications.
Auxiliary Windows
  • Cascade Parameter Graph: A 3-D view of how the gain, NF, etc., propagate through the system at each component output.
  • TX/RX Path Budget: Enter transmitter, antenna, free space path, and receiver parameters to calculate power level, SNR, NF, etc. at receiver output.
  • Dynamic Range: Calculate SNR, dynamic range, spurious-free DR, noise power, etc.
  • I/O Conversion: Convert component parameters from input to output, and vice versa.
  • Spur Calculation: Calculate amplitude and frequency values for spur products that include mixer suppression, system gains/losses, and filter responses.
