News and changes in BetaMatch 3.4.0:

• Plots have been moved out from the View Menu to a separate Plot Menu. See Available Plots.
• Marker frequencies are persistent (last used values will be restored at startup). This option can be turned off by unticking “Remember Marker Frequencies” under General Tab in the options settings (Tools Menu –> Options...). See Markers & Bands.
• Display settings of grid, plot title and axis labels in the trace plots will be remembered between BetaMatch sessions (ie these settings are persistent). The settings are also now common between all trace plots.
• The selected band for Channel number vs Frequency Plot can now be selected directly from the Tools Menu (as well as from the plot’s context menu). Selected band as well as showing title, axis legends and grid are made persistent.
• The selected plot in the Conversion Plots can now be selected directly from the Tools Menu (as well as from the context menu of the plot). Selected type of plot as well as showing title, axis legends and grid are made persistent.
• Many other plot settings are made persistent (see Screen Graphics and User Interface).
• Option to set Port Extension has been added. See Port Extension for more information.
• LTE frequency bands (full bands, RX and TX) have been added to the predefined bands in Markers’ context menu (see Setting Frequency Bands).
• Set any markerpair to any of the predefined frequency bands from the Markers Menu.
• Option to use anti-aliasing for all plots (see Context Menu for Plots).
• The calculation of Bandwidth Potential if faster.

What is BetaMatch?

BetaMatch is a Windows program that calculates and optimizes matching networks for antennas.

The program reads 1-port Touchstone data (from *.s1p files) that can be exported from all modern network analyzers. It is also possible to read 2-port Touchstone files (*.s2p) but only one of the ports will be read (S11 or S22).

Electrical delay and matching components can be added to the loaded 1-port data.

The resulting impedance is presented in plots showing ‘Smith Chart’, ‘Return Loss’, ‘VSWR’ and ‘Accepted Power into the antenna’.

The optimizer will automatically calculate the best matching network for 2, 3, 4 and 5 component networks.

It is also possible to optimize for sources with frequency dependent complex impedance and output power.

Component values are based on measured 2-port data. This provides much better correlation with a real implementation than if ideal components were used.

BetaMatch runs under Windows XP, Vista and Win 7 (32 and 64 bit).

Demo Version and License file

The version you download here will start in a demonstration mode. This means that it is only possible to use the example files that comes with BetaMatch. In order to load and work with your own Touchstone data you will need a license file.

If you wish to evaluate the full version you may obtain an evaluation license. Send an e-mail to MNW Scan with your name, the name of your company and your contact details. A time-limited license file will be sent to you.

How to install the license is described in the Installation instructions.
