 Click
an icon to download RF Workbench only after you have read and agreed to
the Shareware terms.
NOTE: If you have 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,
Ability to run native 16-bit source code OR you can
use DOSBox emulator (see below - very simple) in 64-bit Windows 10.

Here is an announcement for Tx/Rx Designer (the
original for-sale name of the RF Workbench Shareware) in the August
1995 issue of the ARRL's QST magazine. RF Workbench was originally
copyrighted with the USPTO under the name Tx/Rx Designer on 11/28/1994.
The "Spur Web" moniker is part of the copyright.
Note: RF Workbench
WILL NOT run in any 64-bit version of Windows without 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.;
Thanks to Mr. Ted Bruce for discovering this method!

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.
