Abstract
A multiple tap attenuator microchip device is disclosed. The device includes a substrate having two or more attenuator taps formed on a surface of the substrate. One or more ground contacts are also formed on the substrate surface and operatively connected to the attenuator taps. The attenuator taps each include a resistive network that is configured to provide a level of attenuation of an rf signal applied to the attenuator tap that is different from the attenuation level provided by the other attenuator tap(s).

(canceled)
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.

A microchip device comprising:
- a substrate having a first surface;
- a first attenuator tap formed on the first surface of the substrate;
- a second attenuator tap formed on the first surface of the substrate in spaced relation to said first attenuator tap;
- a first ground contact formed on the first surface in spaced relation to said first attenuator tap;
- a second ground contact formed on the first surface on an opposing side of the first attenuator tap from said first ground contact and spaced from said first and second attenuator taps;
- and
- a third ground contact formed on the first surface on an opposing side of the second attenuator tap from said first ground contact and spaced from said second attenuator tap;
- wherein said first attenuator tap comprises a first resistive network configured to provide a first level of attenuation of an rf signal applied to said first attenuator tap and said second attenuator tap comprises a second resistive network configured to provide a second level of attenuation of an rf signal applied to said second attenuator tap, said second level of attenuation being different in magnitude from the first level of attenuation.
