- a separate mechanical attachment of the tab 18 on Bottom section 3 is not shown and can also be omitted because both elements can be held in their position relative to one another by magnetic attraction. About that however, the position of the tab 18 can also be secured by adhesive or security lacquer or the like. be made.
- the inner conductor 12 points to the formation of the three gates of the microwave component three connecting conductors 23, 24, 25. These are arranged accordingly Recesses 26, 27, 28 in the first, third and fourth wall sections 4, 6 and 7 respectively led out of the housing 1, 2 of the microwave component, whereby a electrical insulation of the inner conductor 12 against the housing 1, 2 is ensured.

Then the support elements 29, 30 in the Housing part 1 introduced. In the between the support members 29, 30 and Floor section 3 or the tab 18 lying area is then the Thermoflux disc 16 and the permanent magnet 15 arranged and it becomes this Space area covered by the intermediate element 14. To ensure the Air gap 17 must be the height of the support elements 29, 30 in the viewing direction View W may be greater than the sum of the heights of tab 18, the Thermoflux disc 16 and the permanent magnet 15. Instead of for reasons The simplicity shown single thermoflux disc 16 can be used in practice an arrangement of several Thermoflux disks can also be used.

After attaching the lid part 2 that Microwave device subtracted from these pins.
- the permanent magnet 15 is installed in the fully magnetized state.
- the required magnetic field for the operation of the microwave component is with the slidable tab adjusted.
- For mechanical access to this Tab 18 can also use the recess 20 in the bottom section 3 as long as these - due to the installation position of the microwave component - is accessible.
- the exemplary embodiments shown in the figures differ in terms of the formation of the subspace 31 by the shape chosen for the Permanent magnets 15. While in the first embodiment shown in FIGS. 1 to 7 the disc-shaped permanent magnet has a radial extension, which in essentially coincides with that of the ferrite disks 11, 13 is in the second 1, 2, 8 to 12, a permanent magnet with lower radial dimensions used. To reach a comparable volume for the Coming permanent magnet 15 is the thickness of the disc-shaped Permanent magnets 15 selected larger in the second embodiment than in the first Embodiment. Correspondingly, subspace 31 extends in the first Embodiment to a significant extent in the space between the permanent magnet 15 and the tab 18, i.e. in the air gap 17.
- the subspace 31 in the second exemplary embodiment compares this with FIG much larger proportion of a space between the floor section 3 and the intermediate element 14, which is laterally through the first wall section 4th on the one hand and by the permanent magnet 15 and the tab 18 on the other is narrowed down.
- By reducing the radial dimension of the Permanent magnet 15 in the second embodiment is also one Enlargement of the subspace 31 to accommodate a load impedance compared to the first embodiment possible.
