A microwave single stage gain calculator has been developed by SPG to enable quick calculations of microwave amplifier gain stages. A set of s parameters for the active device/devices is required.

These parameters are inserted into the javascript calculator. The calculator allows the assessment of the gains to be made rapidly without the need of a lot of tedious hand calculations. Please access the calculator from the SPG website under the complementary items menu.

This is a tutorial description of the calculations for single stage microwave gains using s parameters. Allows one to see what the ramifications of using I/O impedance and matching is to the gain obtainable from a microwave device.

There are multiple gains that must be taken care of including power gain, available gain, transducer gain, unilateral transducer gain etc. Associated with this tutorial is a javascript calculator to quickly assess the performance of the device so long as the  s parameters are known. This will be presented in a subsequent post. The calculator will be available for free use.Please visit the SPG website and check under the complementary menu item ( Use cntrl – F ) for single page search for convenience.
