## Design of a Resistive Attenuator |
||

In RF/Microwave applications, there are times an attenuator is needed to reduce the magnitude of the signal while maintaining the impedance matching at both the input and the output ports. A simple attenuator can be realized with three resistors with two of them equal in values. This applet implements the design equations for such resistive network.
## Brief User's GuideFirst, the user needs to specify the characteristic impedance Z0. Then, there are three parameters to joggle: {R1, R2, alpha} with alpha being the attenuation in dB. When one of the parameters is fixed, the other two can be solved for. - A click on the "Solve for R2, alpha" causes the program to find R2, alpha with the given R1 value
- A click on the "Solve for R1, alpha" causes the program to find R1, alpha with the given R2 value
- A click on the "Solve for R1, R2" causes the program to find R1, R2 with the given alpha value
