WinAtt
  

WinAtt is a small utility to aid in attenuator design. It calculates the exact values of resistor required for a given attenuation and system impedance, and also shows the performance of attenuators built using real-world components with preferred values. Both pi and T designs are covered, and the power dissipated in each resistor is shown. Recalculation is automatic if the attenuation or power is changed.
Simply enter a value for your desired attenuation (and power input, if you wish) in the box at the top left. If you want to design for a system impedance other than 50 ohms, then change the value in the system impedance box just below the title.
