Patent ID: 8143969

Claim:
A microchip device comprising: a substrate having a surface; a first attenuator formed on the surface of said substrate; a second attenuator formed on the surface of said substrate in spaced relation to said first attenuator; and a grounding contact formed on the surface of said substrate in spaced relation to said first and second attenuators; said first attenuator comprising a first input contact, a first output contact in spaced relation to said first input contact, and a first resistive network configured to provide a first level of attenuation to an rf signal applied to the first input contact; and said second attenuator comprising a second input contact, a second output contact in spaced relation to said second input contact, and a second resistive network configured to provide a second level of attenuation to an rf signal applied to the second input contact, said second level of attenuation being different from said first level of attenuation; wherein the first resistive network comprises a first resistor, a second resistor, a first junction pad connected between the first and second resistors, and a first shunt resistor connected between the first junction pad and said grounding contact; and the second resistive network comprises a third resistor, a fourth resistor, a second junction pad connected between the third and fourth resistors, and a second shunt resistor connected between the second junction pad and the first junction pad and to the first shunt resistor through said first junction pad.
