Notes

1. A resistive attenuator achieves a specified attenuation while maintaining desired input and output impedance levels.
2. The design specifies the resistance values to achieve the specified level of attenuation for the input and output resistances.
3. The input resistance Rin must be greater than or equal to the output resistance Rout.
4. There is a minimum attenuation that can be achieved for the specified input and output resistances. This attenuation is given by:

Example

A 3-dB tee attenuator was designed for a 50 Ohm input and output resistance.
