Definitions
- the invention relates to a monolithically integrated microwave component with the features mentioned in the preamble of claim 1
- Microwave conductor components of the generic type are known. These are used for emitting or decoupling electromagnetic waves of high frequency that are brought in via a microwave conductor.
- microwave conductor components consist of a chip with an integrated conductor structured as a strip conductor or microstrip conductor. This conductor is known to be placed on the top of the chip Further circuit components, for example Veistarker, oscillators or the like can be integrated within the chip.
- the Ch p is arranged on or next to a carrier, which likewise has a conductor for the electromagnetic waves designed as a strip conductor or microstrip conductor. Around the line structures of the chip and the carrier with one another to connect, it is known to contact them via a bond or ribbon connection.
- the compensation structures are formed by line sections of the microwave conductors which have a conductor width adapted to the transition.
- the compensation structure can be integrated in a simple manner by determining the layout of the microwave guides in the contact area.
- the microwave guide assigned to the chip forms a capacitively acting line section in the contact area and the microwave guide assigned to the carrier forms an inductively acting line section in the contact area.
- FIG. 1 shows a schematic section through a monolithically integrated microwave conductor component
- Figure 2 is a schematic plan view of the monolithically integrated microwave conductor component.
- FIG. 1 shows a monolithically integrated microwave conductor component 10 in a longitudinal section.
- the contact area 12 of a first micro-conductor 14 with a second microwave conductor 16 is shown.
- the microwave conductor 14 is arranged on a chip 18, for example on a GaAs (gallium arsenide) chip.
- the chip 18 has a thickness of 100 ⁇ m, for example.
- the second microwave conductor 16 is arranged on a carrier 20, for example an Al 2 O 3 (aluminum oxide) substrate.
- the carrier 20 has a thickness of 254 ⁇ m, for example.
- An upper side 22 of the carrier 20 carries a metallization 24, while an underside 26 of the carrier 20 carries a metallization 28.
- the metallizations 24 and 28 are galvanically connected via vias 30 indicated here.
- the metallic Sations 24 and 28 are used in a known manner to provide a ground potential for integrated in the microwave conductor component 10 - not shown in detail - circuits. These can be monolithically integrated in the chip 18, for example.
- the microwave conductor 14 consists of a first line section 32 and a second line section 34 and the microwave conductor 16 consists of a first line section 36 and a second line section 38.
- the line sections 34 and 38 are in the contact area 12.
- the metallization 24 forms in the contact area 12 a recess 40 which can be seen in FIG. 2 and which virtually encompasses the contact area 12.
- the plated-through holes 30 are arranged symmetrically around the contact region 12 by the carrier 20.
- the microwave conductor 14 comprises a width a in its line section 32 and a width b in its line section 34, the line section 34 being wider than the line section 32.
- a taper structure 42 is formed in the transition between the line sections 32 and 34.
- the microwave waveguide 16 has a width c in its line section 36 and a width d in its line section 38.
- the width d is less than the width c.
- the line section 38 forms a contact clock zone 44.
- the microwave conductors 14 and 16 are connected to one another via a via 46 through the chip 18.
- the via 46 connects the line sections 34 and 38.
- the line sections 32 and 34 of the microwave conductor 14 and the line section 36 of the microwave conductor 16 are strip or microstrip conductors, while the line section 38 is designed as a coplanar conductor.
- the line sections 34 and 38 form integrated compensation structures for compensating reflections in the contact area 12.
- the section 32 forms a 50-ohm microstrip line by arrangement over the metallization 24 (ground).
- the line section 36 of the micelle conductor 16 likewise forms a 50-ohm microstrip line, with a matching to the metallization 28 on the underside of the carrier 20.
- the inventive design of the contact area 12 allows electromagnetic waves to be coupled out or out.
- either the microwave 14 input and the microwave 14 output are coupled out or out.
- reflection values of ⁇ 27 db result for the monolithically integrated microwave waveguide component according to the invention.
- the transmission loss in transition here is less than 0.3 db.
- the chip 18 can be applied to the carrier 20 itself in an adjusting manner when the microwave conductor component 10 is mounted. Contacting takes place by soldering, the chip 18 being adjusted on the carrier 20 itself — adjusting by the surface tension of the solder in the region of the contact area 12. As a result, tolerance deviations during assembly can be reduced to a minimum, so that the formation of parasitic elements in the contact area 12 - which could have an effect on the compensation - is negligibly small.
