Abstract
Abstract A high frequency device, such as a microwave semiconductor device or integrated circuit, is mounted on a base plate with at least one terminal extending through the base plate and electrically connected to the device. The base plate is mounted in and extends across one end of a passage in a metal housing. A pair of coaxial terminals are mounted on the housing and have terminal pins which extend through the housing to the passage and are electrically connected to the device. The base plate terminals permit DC biasing the device with the coaxial terminals providing the RF connections to the device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
A high frequency device assembly comprising a housing having a passage therethrough, a base plate mounted in and extending across the passage in the housing, a high frequency device mounted on said base plate within said passage, at least one terminal extending through said base plate and electrically connected to said high frequency device, and at least one coaxial terminal mounted on said housing, said coaxial terminal having a conductor pin extending through said housing to said passage and electrically connected to said high frequency device, said base plate having a metal rib projecting from and extending diametrically across its surface on which the high frequency device is mounted, said rib having a notch thereacross, said high frequency device being mounted within the notch and a pair of microstrip circuit plates being mounted on the base plate on opposite sides of the rib, each of said microstrip circuit plates including a metal film strip electrically connected to the high frequency device and to a separate coaxial terminal pin.
Claim 2
Dependent Claim
168 words
A high frequency device assembly comprising a housing having a passage therethrough, a base plate mounted in and extending across the passage in the housing, a high frequency device mounted on said base plate within said passage, at least one terminal extending through said base plate and electrically connected to said high frequency device, and at least one coaxial terminal mounted on said housing, said coaxial terminal having a conductor pin extending through said housing to said passage and electrically connected to said high frequency device, said base plate having a metal rib projecting from and extending diametrically across its surface on which the high frequency device is mounted, said rib having a notch thereacross, said high frequency device being mounted within the notch and a pair of microstrip circuit plates being mounted on the base plate on opposite sides of the rib, each of said microstrip circuit plates including a metal film strip electrically connected to the high frequency device and to a separate coaxial terminal pin.
Claim 3
Dependent Claim
43 words
A high frequency device assembly in accordance with claim 1 including a pair of opposed notches in and extending longitudinally along the wall of the passage in the housing, and the ends of the rib on the base plate fit into said notches.
Claim 4
Dependent Claim
67 words
A high frequency device assembly in accordance with claim 1 including a metal plate within the passage in the housing over the rib on the base plate, said metal plate being seated on the rib and extending diametrically across the base plate to electrically screen the microstrip circuit plate on one side of the rib from the microstrip circuit plate on the other side of the rib.
Claim 5
Dependent Claim
76 words
A high frequency device in accorDance with claim 1 in which the passage in the housing is counterbored at one end to provide a ledge spaced from said one end, the base plate is within the counterbored end of the passage and is seated against the ledge, and an annular locking ring is secured within the counterbored end of the passage and is seated against the base plate to secure the base plate within the passage.
