The calibration standards and the power detector are integrated on the substrate.
Claims14
A calibration module with a substrate and at least one high-frequency terminal arranged on the substrate, which is connected with an allocated switching unit arranged on the substrate in a first switching configuration to at least one structure associated with an allocated calibration standard and by changing the first switching configuration to a second switching configuration to an allocated power detector,
- wherein the at least one structure associated with the calibration standard and the power detector are arranged on the substrate,
- wherein the power detector is arranged on a sub-region of the substrate,
- wherein an air-filled recess is provided in the sub-region of the substrate, and
- wherein the power detector is provided as an additional structure associated with a calibration standard.
