Calculates the resistor values, attenuation, 'impedance', reflection coefficient, VSWR and return loss of a T attenuator. This can be built into a FLEXI-BOX and a transmission line PCB is available which easily adapts for this circuit. There is also a selection of suitable connectors available.

This calculator uses Visual Basic and will work in Internet Explorer and other browsers with Visual Basic plug-ins. For more information see About our calculators. A further simple T Attenuator Calculator is available in JavaScript.

This calculator uses simple Ohms law calculations, and more comprehensive formulas for Voltage Reflection Coefficient and VSWR which are available at:-
