RF Trap With Attenuator Calculator

Calculates the attenuation, 'impedance', reflection coefficient, VSWR and return loss of a circuit that incorporates a RF tank circuit into a Pi attenuator. Preferred resistor values are entered into the text boxes, similar to the way that values for a prototype may be selected. Capacitor and Inductor values for the tank circuit may be selected with the Tank Circuit Resonant Frequency Calculator.

Characteristic impedance of the system:   Ohms Attenuation:   dB
Enter the value of R2/R3 resistor:   Ohms Impedance:   Ohms
Enter the value of R1/R4:   Ohms VSWR: 
Reflection Coefficient: 
Return Loss:   dB
 

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.

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